https://doc.qt.io/archives/qtjambi-4.5.2_01/com/trolltech/qt/qmake-variable-reference.html qmake Variable Reference qmake's fundamental behavior is influenced by variable declarations that define the build process of each project. Some of these declare resources, such as headers and source files, that are common to each platform; others are used to customize the behavior of compilers and linkers on specific platforms. Platform-specific variables follow the naming pattern of the variables which they extend or modify, but include the name of the relevant platform in their name. For example, QMAKE_LIBS can be used to specify a list of libraries that a project needs to link against, and QMAKE_LIBS_X11 can be used to extend or override this list. CONFIG The CONFIG variable specifies project configuration and compiler options. The values will be recognized internally by qmake and have special meaning. They are as follows. These CONFIG values control compilation flags: Option Description release The project is to be built in release mode. This is ignored if debug is also specified. debug The project is to be built in debug mode. debug_and_release The project is built in both debug and release modes. This can have some unexpected side effects (see below for more information). build_all If debug_and_release is specified, the project is built in both debug and release modes by default. ordered When using the subdirs template, this option specifies that the directories listed should be processed in the order in which they are given. precompile_header Enables support for the use of precompiled headers in projects. warn_on The compiler should output as many warnings as possible. This is ignored if warn_off is specified. warn_off The compiler should output as few warnings as possible. Since the debug option overrides the release option when both are defined in the CONFIG variable, it is necessary to use the debug_and_release option if you want to allow both debug and release versions of a project to be built. In such a case, the Makefile that qmake generates includes a rule that builds both versions, and this can be invoked in the following way: make all On Windows (or if Qt is configured with -debug_and_release, adding the build_all option to the CONFIG variable makes this rule the default when building the project, and installation targets will be created for both debug and release builds. Additionally, adding debug_and_release to the CONFIG variable will cause both debug and release to be defined in the contents of CONFIG. When the project file is processed, the scopes that test for each value will be processed for both debug and release modes. The build_pass variable will be set for each of these mode, and you can test for this to perform build-specific tasks. For example: build_pass:CONFIG(debug, debug|release) {     unix: TARGET = $$join(TARGET,,,_debug)     else: TARGET = $$join(TARGET,,,d) } As a result, it may be useful to define mode-specific variables, such as QMAKE_LFLAGS_RELEASE, instead of general variables, such as QMAKE_LFLAGS, where possible. The following options define the application/library type: Option Description qt The target is a Qt application/library and requires the Qt library and header files. The proper include and library paths for the Qt library will automatically be added to the project. This is defined by default, and can be fine-tuned with the \l{#qt}{QT} variable. thread The target is a multi-threaded application or library. The proper defines and compiler flags will automatically be added to the project. x11 The target is a X11 application or library. The proper include paths and libraries will automatically be added to the project. windows The target is a Win32 window application (app only). The proper include paths, compiler flags and libraries will automatically be added to the project. console The target is a Win32 console application (app only). The proper include paths, compiler flags and libraries will automatically be added to the project. shared The target is a shared object/DLL. The proper include paths, compiler flags and libraries will automatically be added to the project. dll dylib static The target is a static library (lib only). The proper compiler flags will automatically be added to the project. staticlib plugin The target is a plugin (lib only). This enables dll as well. designer The target is a plugin for Qt Designer. uic3 Configures qmake to run uic3 on the content of FORMS3 if defined; otherwise the contents of FORMS will be processed instead. no_lflags_merge Ensures that the list of libraries stored in the LIBS variable is not reduced to a list of unique values before it is used. resources Configures qmake to run rcc on the content of RESOURCES if defined. These options are used to set the compiler flags: Option Description 3dnow AMD 3DNow! instruction support is enabled. exceptions Exception support is enabled. mmx Intel MMX instruction support is enabled. rtti RTTI support is enabled. stl STL support is enabled. sse SSE support is enabled. sse2 SSE2 support is enabled. These options define specific features on Windows only: Option Description flat When using the vcapp template this will put all the source files into the source group and the header files into the header group regardless of what directory they reside in. Turning this option off will group the files within the source/header group depending on the directory they reside. This is turned on by default. embed_manifest_dll Embeds a manifest file in the DLL created as part of a library project. embed_manifest_exe Embeds a manifest file in the DLL created as part of an application project. incremental Used to enable or disable incremental linking in Visual C++, depending on whether this feature is enabled or disabled by default. See qmake Platform Notes for more information on the options for embedding manifest files. These options only have an effect on Mac OS X: Option Description ppc Builds a PowerPC binary. x86 Builds an i386 compatible binary. app_bundle Puts the executable into a bundle (this is the default). lib_bundle Puts the library into a library bundle. The build process for bundles is also influenced by the contents of the QMAKE_BUNDLE_DATA variable. These options have an effect on Linux/Unix platforms: Option Description largefile Includes support for large files. separate_debug_info Puts debugging information for libraries in separate files. The CONFIG variable will also be checked when resolving scopes. You may assign anything to this variable. For example: CONFIG += qt console newstuff ... newstuff {     SOURCES += new.cpp     HEADERS += new.h } DEFINES qmake adds the values of this variable as compiler C preprocessor macros (-D option). For example: DEFINES += USE_MY_STUFF QT_DLL DEF_FILE This is only used on Windows when using the app template. Specifies a .def file to be included in the project. DEPENDPATH This variable contains the list of all directories to look in to resolve dependencies. This will be used when crawling through included files. DEPLOYMENT This is only used on Windows CE. Specifies which additional files will be deployed. Deployment means the transfer of files from the development system to the target device or emulator. Files can be deployed by either creating a Visual Studio project or using the cetest executable. For example: myFiles.sources = path\*.png DEPLOYMENT += myFiles This will upload all PNG images in path to the same directory your build target will be deployed to. The default deployment target path for Windows CE is %CSIDL_PROGRAM_FILES%\target, which usually gets expanded to \Program Files\target. It is also possible to specify multiple sources to be deployed on target paths. In addition, different variables can be used for deployment to different directories. For example: myFiles.sources = path\file1.ext1 path2\file2.ext1 path3\* myFiles.path = \some\path\on\device someother.sources = C:\additional\files\* someother.path = \myFiles\path2 DEPLOYMENT += myFiles someother Note: All linked Qt libraries will be deployed to the path specified by myFiles.path. DEPLOYMENT_PLUGIN This is only used on Windows CE. This variable specifies the Qt plugins that will be deployed. All plugins available in Qt can be explicitly deployed to the device. See Static Plugins for a complete list. Note: No plugins will be deployed automatically. If the application depends on plugins, these plugins have to be specified manually. For example: DEPLOYMENT_PLUGIN += qjpeg This will upload the jpeg imageformat plugin to the plugins directory on the Windows CE device. DESTDIR Specifies where to put the target file. For example: DESTDIR = ../../lib DESTDIR_TARGET This variable is set internally by qmake, which is basically the DESTDIR variable with the TARGET variable appened at the end. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. DLLDESTDIR Specifies where to copy the target dll. DISTFILES This variable contains a list of files to be included in the dist target. This feature is supported by UnixMake specs only. For example: DISTFILES += ../program.txt DSP_TEMPLATE This variable is set internally by qmake, which specifies where the dsp template file for basing generated dsp files is stored. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. FORMS This variable specifies the .ui files (see Qt Designer) to be processed through uic before compiling. All dependencies, headers and source files required to build these .ui files will automatically be added to the project. For example: FORMS = mydialog.ui \     mywidget.ui \         myconfig.ui If FORMS3 is defined in your project, then this variable must contain forms for uic, and not uic3. If CONFIG contains uic3, and FORMS3 is not defined, the this variable must contain only uic3 type forms. FORMS3 This variable specifies the old style .ui files to be processed through uic3 before compiling, when CONFIG contains uic3. All dependencies, headers and source files required to build these .ui files will automatically be added to the project. For example: FORMS3 = my_uic3_dialog.ui \      my_uic3_widget.ui \          my_uic3_config.ui GUID Specifies the GUID that is set inside a .vcproj file. The GUID is usually randomly determined. However, should you require a fixed GUID, it can be set using this variable. This variable is specific to .vcproj files only; it is ignored otherwise. HEADERS Defines the header files for the project. qmake will generate dependency information (unless -nodepend is specified on the command line) for the specified headers. qmake will also automatically detect if moc is required by the classes in these headers, and add the appropriate dependencies and files to the project for generating and linking the moc files. For example: HEADERS = myclass.h \           login.h \           mainwindow.h See also SOURCES. INCLUDEPATH This variable specifies the #include directories which should be searched when compiling the project. Use ';' or a space as the directory separator. For example: INCLUDEPATH = c:/msdev/include d:/stl/include INSTALLS This variable contains a list of resources that will be installed when make install or a similar installation procedure is executed. Each item in the list is typically defined with attributes that provide information about where it will be installed. For example, the following target.path definition describes where the build target will be installed, and the INSTALLS assignment adds the build target to the list of existing resources to be installed: target.path += $$[QT_INSTALL_PLUGINS]/imageformats INSTALLS += target LEXIMPLS This variable contains a list of lex implementation files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. LEXOBJECTS This variable contains the names of intermediate lex object files.The value of this variable is typically handled by qmake and rarely needs to be modified. LEXSOURCES This variable contains a list of lex source files. All dependencies, headers and source files will automatically be added to the project for building these lex files. For example: LEXSOURCES = lexer.l LIBS This variable contains a list of libraries to be linked into the project. You can use the Unix -l (library) and -L (library path) flags and qmake will do the correct thing with these libraries on Windows (namely this means passing the full path of the library to the linker). The only limitation to this is the library must exist, for qmake to find which directory a -l lib lives in. For example: unix:LIBS += -L/usr/local/lib -lmath win32:LIBS += c:/mylibs/math.lib Note: On Windows, specifying libraries with the -l option, as in the above example, will cause the library with the highest version number to be used; for example, libmath2.lib could potentially be used instead of libmathlib. To avoid this ambiguity, we recommend that you explicitly specify the library to be used by including the .lib file name suffix. By default, the list of libraries stored in LIBS is reduced to a list of unique names before it is used. To change this behavior, add the no_lflags_merge option to the CONFIG variable: CONFIG += no_lflags_merge LITERAL_HASH This variable is used whenever a literal hash character (#) is needed in a variable declaration, perhaps as part of a file name or in a string passed to some external application. For example:Error parsing snippet. By using LITERAL_HASH in this way, the # character can be used to construct a URL for the message() function to print to the console. MAKEFILE This variable specifies the name of the Makefile which qmake should use when outputting the dependency information for building a project. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. MAKEFILE_GENERATOR This variable contains the name of the Makefile generator to use when generating a Makefile. The value of this variable is typically handled internally by qmake and rarely needs to be modified. MOC_DIR This variable specifies the directory where all intermediate moc files should be placed. For example: unix:MOC_DIR = ../myproject/tmp win32:MOC_DIR = c:/myproject/tmp OBJECTS This variable is generated from the SOURCES variable. The extension of each source file will have been replaced by .o (Unix) or .obj (Win32). The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. OBJECTS_DIR This variable specifies the directory where all intermediate objects should be placed. For example: unix:OBJECTS_DIR = ../myproject/tmp win32:OBJECTS_DIR = c:/myproject/tmp OBJMOC This variable is set by qmake if files can be found that contain the Q_OBJECT macro. OBJMOC contains the name of all intermediate moc object files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. POST_TARGETDEPS All libraries that the target depends on can be listed in this variable. Some backends do not support this, these include MSVC Dsp, and ProjectBuilder .pbproj files. Generally this is supported internally by these build tools, this is useful for explicitly listing dependant static libraries. This list will go after all builtin (and $$PRE_TARGETDEPS) dependencies. PRE_TARGETDEPS All libraries that the target depends on can be listed in this variable. Some backends do not support this, these include MSVC Dsp, and ProjectBuilder .pbproj files. Generally this is supported internally by these build tools, this is useful for explicitly listing dependant static libraries. This list will go before all builtin dependencies. PRECOMPILED_HEADER This variable indicates the header file for creating a precompiled header file, to increase the compilation speed of a project. Precompiled headers are currently only supported on some platforms (Windows - all MSVC project types, Mac OS X - Xcode, Makefile, Unix - gcc 3.3 and up). On other platforms, this variable has different meaning, as noted below. This variable contains a list of header files that require some sort of pre-compilation step (such as with moc). The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

Use the QMAKESPEC environment variable to override the qmake configuration. Note that, due to the way qmake reads project files, setting the QMAKESPEC environment variable from within a project file will have no effect. QMAKE_APP_FLAG This variable is empty unless the appTEMPLATE is specified. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. Use the following instead: app {     # Conditional code for 'app' template here } QMAKE_APP_OR_DLL This variable is empty unless the app or dllTEMPLATE is specified. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_AR_CMD This is used on Unix platforms only. This variable contains the command for invoking the program which creates, modifies and extracts archives. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_BUNDLE_DATA This variable is used to hold the data that will be installed with a library bundle, and is often used to specify a collection of header files. For example, the following lines add path/to/header_one.h and path/to/header_two.h to a group containing information about the headers supplied with the framework: FRAMEWORK_HEADERS.version = Versions FRAMEWORK_HEADERS.files = path/to/header_one.h path/to/header_two.h FRAMEWORK_HEADERS.path = Headers QMAKE_BUNDLE_DATA += FRAMEWORK_HEADERS The last line adds the information about the headers to the collection of resources that will be installed with the library bundle. Library bundles are created when the lib_bundle option is added to the CONFIG variable. See qmake Platform Notes for more information about creating library bundles. This is used on Mac OS X only. QMAKE_BUNDLE_EXTENSION This variable defines the extension to be used for library bundles. This allows frameworks to be created with custom extensions instead of the standard .framework directory name extension.

QMAKE_LINK_SHLIB_CMD This variable contains the command to execute when creating a shared library. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_POST_LINK This variable contains the command to execute after linking the TARGET together. This variable is normally empty and therefore nothing is executed, additionally some backends will not support this - mostly only Makefile backends. QMAKE_PRE_LINK This variable contains the command to execute before linking the TARGET together. This variable is normally empty and therefore nothing is executed, additionally some backends will not support this - mostly only Makefile backends. QMAKE_LN_SHLIB This variable contains the command to execute when creating a link to a shared library. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_MAC_SDK This variable is used on Mac OS X when building universal binaries. This process is described in more detail in the Deploying an Application on Mac OS X document. QMAKE_MACOSX_DEPLOYMENT_TARGET This variable only has an effect when building on Mac OS X. On that platform, the variable will be forwarded to the MACOSX_DEPLOYMENT_TARGET environment variable, which is interpreted by the compiler or linker. For more information, see the Deploying an Application on Mac OS X document. QMAKE_MAKEFILE This variable contains the name of the Makefile to create. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_MOC_SRC This variable contains the names of all moc source files to generate and include in the project.

The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_QT_DLL This variable is not empty if Qt was built as a dll. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_RESOURCE_FLAGS This variable is used to customize the list of options passed to the Resource Compiler in each of the build rules where it is used. For example, the following line ensures that the -threshold and -compress options are used with particular values each time that rcc is invoked: QMAKE_RESOURCE_FLAGS += -threshold 0 -compress 9 QMAKE_RUN_CC This variable specifies the individual rule needed to build an object. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_RUN_CC_IMP This variable specifies the individual rule needed to build an object. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_RUN_CXX This variable specifies the individual rule needed to build an object. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_RUN_CXX_IMP This variable specifies the individual rule needed to build an object. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_TARGET This variable contains the name of the project target. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. QMAKE_UIC This variable contains the location of uic if it is not in the path. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. It can be used to specify arguments to uic as well, such as additional plugin paths. For example: QMAKE_UIC = uic -L /path/to/plugin QT The values stored in the QT variable control which of the Qt modules are used by your project. The table below shows the options that can be used with the QT variable and the features that are associated with each of them: Option Features core (included by default) QtCore module gui (included by default) QtGui module network QtNetwork module opengl QtOpenGL module phonon Phonon Multimedia Framework sql QtSql module svg QtSvg module xml QtXml module webkit WebKit integration qt3support Qt3Support module By default, QT contains both core and gui, ensuring that standard GUI applications can be built without further configuration. If you want to build a project without the QtGui module, you need to exclude the gui value with the "-=" operator; the following line will result in a minimal Qt project being built: QT -= gui # Only the core module is used. Note that adding the opengl option to the QT variable automatically causes the equivalent option to be added to the CONFIG variable. Therefore, for Qt applications, it is not necessary to add the opengl option to both CONFIG and QT. QTPLUGIN This variable contains a list of names of static plugins that are to be compiled with an application so that they are available as built-in resources. QT_VERSION This variable contains the current version of Qt. QT_MAJOR_VERSION This variable contains the current major version of Qt. QT_MINOR_VERSION This variable contains the current minor version of Qt. QT_PATCH_VERSION This variable contains the current patch version of Qt. RC_FILE This variable contains the name of the resource file for the application. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. RCC_DIR This variable specifies the directory where all intermediate resource files should be placed. For example: unix:RCC_DIR = ../myproject/resources win32:RCC_DIR = c:/myproject/resources REQUIRES This is a special variable processed by qmake. If the contents of this variable do not appear in CONFIG by the time this variable is assigned, then a minimal Makefile will be generated that states what dependencies (the values assigned to REQUIRES) are missing. This is mainly used in Qt's build system for building the examples. RES_FILE This variable contains the name of the resource file for the application. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. SIGNATURE_FILE This is only used on Windows CE. Specifies which signature file should be used to sign the project target. Note: This variable will overwrite the setting you have specified in configure, with the -signature option. SOURCES This variable contains the name of all source files in the project. For example: SOURCES = myclass.cpp \       login.cpp \       mainwindow.cpp See also HEADERS SRCMOC This variable is set by qmake if files can be found that contain the Q_OBJECT macro. SRCMOC contains the name of all the generated moc files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. SUBDIRS This variable, when used with the subdirs templatesubdirs contains the names of all subdirectories that contain parts of the project that need be built. Each subdirectory must contain its own project file. For example: SUBDIRS = kernel \           tools It is essential that the project file in each subdirectory has the same name as the subdirectory itself, so that qmake can find it. For example, if the subdirectory is called myapp then the project file in that directory should be called myapp.pro. If you need to ensure that the subdirectories are built in the order in which they are specified, update the CONFIG variable to include the ordered option: CONFIG += ordered TARGET This specifies the name of the target file. For example: TEMPLATE = app TARGET = myapp SOURCES = main.cpp The project file above would produce an executable named myapp on unix and 'myapp.exe' on windows. TARGET_EXT This variable specifies the target's extension. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. TARGET_x This variable specifies the target's extension with a major version number. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. TARGET_x.y.z This variable specifies the target's extension with version number. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. TEMPLATE This variable contains the name of the template to use when generating the project. The allowed values are: Option Description app Creates a Makefile for building applications (the default). (See qmake Common Projects for more information.) lib Creates a Makefile for building libraries. (See qmake Common Projects for more information.) subdirs Creates a Makefile for building targets in subdirectories. The subdirectories are specified using the SUBDIRS variable. vcapp Windows only Creates an application project for Visual Studio. (See qmake Platform Notes for more information.) vclib Windows only Creates a library project for Visual Studio. (See qmake Platform Notes for more information.) For example: TEMPLATE = lib SOURCES = main.cpp TARGET = mylib The template can be overridden by specifying a new template type with the -t command line option. This overrides the template type after the .pro file has been processed. With .pro files that use the template type to determine how the project is built, it is necessary to declare TEMPLATE on the command line rather than use the -t option. TRANSLATIONS This variable contains a list of translation (.ts) files that contain translations of the user interface text into non-native languages. See the Qt Linguist Manual for more information about internationalization (i18n) and localization (l10n) with Qt. UICIMPLS This variable contains a list of the generated implementation files by UIC. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. UICOBJECTS This variable is generated from the UICIMPLS variable. The extension of each file will have been replaced by .o (Unix) or .obj (Win32). The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. UI_DIR This variable specifies the directory where all intermediate files from uic should be placed. This variable overrides both UI_SOURCES_DIR and UI_HEADERS_DIR. For example: unix:UI_DIR = ../myproject/ui win32:UI_DIR = c:/myproject/ui UI_HEADERS_DIR This variable specifies the directory where all declaration files (as generated by uic) should be placed. For example: unix:UI_HEADERS_DIR = ../myproject/ui/include win32:UI_HEADERS_DIR = c:/myproject/ui/include UI_SOURCES_DIR This variable specifies the directory where all implementation files (as generated by uic) should be placed. For example: unix:UI_SOURCES_DIR = ../myproject/ui/src win32:UI_SOURCES_DIR = c:/myproject/ui/src VERSION This variable contains the version number of the application or library if either the appTEMPLATE or the libTEMPLATE is specified. For example: VERSION = 1.2.3 VER_MAJ This variable contains the major version number of the library, if the libtemplate is specified. VER_MIN This variable contains the minor version number of the library, if the libtemplate is specified. VER_PAT This variable contains the patch version number of the library, if the libtemplate is specified. VPATH This variable tells qmake where to search for files it cannot open. With this you may tell qmake where it may look for things like SOURCES, and if it finds an entry in SOURCES that cannot be opened it will look through the entire VPATH list to see if it can find the file on its own. See also DEPENDPATH. YACCIMPLS This variable contains a list of yacc source files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. YACCOBJECTS This variable contains a list of yacc object files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. YACCSOURCES This variable contains a list of yacc source files to be included in the project. All dependencies, headers and source files will automatically be included in the project. For example: YACCSOURCES = moc.y _PRO_FILE_ This variable contains the path to the project file in use. For example, the following line causes the location of the project file to be written to the console:Error parsing snippet. _PRO_FILE_PWD_ This variable contains the path to the directory containing the project file in use. For example, the following line causes the location of the directory containing the project file to be written to the console:Error parsing snippet.
