Qt CMakeLists.txt for your Qt project CMakeLists.txt for Qt 5
Example
A minimal CMake project file that uses Qt5 can be:
cmake_minimum_required(VERSION 2.8.11)
project(myproject)
find_package(Qt5 5.7.0 REQUIRED COMPONENTS
Core
)
set(CMAKE_AUTOMOC ON)
add_executable(${PROJECT_NAME}
main.cpp
)
target_link_libraries(${PROJECT_NAME}
Qt5::Core
)
cmake_minimum_required is called to set minimum required version for CMake. The minimum required version for this example to work is 2.8.11 -- previous versions of CMake need additional code for a target to use Qt.
find_package is called to search an installation of Qt5 with a given version -- 5.7.0 in the example -- and wanted components -- Core module in the example. For a list of available modules, see Qt Documentation. Qt5 is marked as REQUIRED in this project. The path to the installation can be hinted by setting the variable Qt5_DIR.
AUTOMOC is a boolean specifying whether CMake will handle the Qt moc preprocessor automatically, i.e. without having to use the QT5_WRAP_CPP() macro.
Other "AUTOMOC-like" variables are:
-
AUTOUIC: a boolean specifying whether CMake will handle the Qtuiccode generator automatically, i.e. without having to use theQT5_WRAP_UI()macro. -
AUTORCC: a boolean specifying whether CMake will handle the Qtrcccode generator automatically, i.e. without having to use theQT5_ADD_RESOURCES()macro.
add_executable is called to create an executable target from the given source files. The target is then linked to the listed Qt's modules with the command target_link_libraries. From CMake 2.8.11, target_link_libraries with Qt's imported targets handles linker parameters, as well as include directories and compiler options.
