| A typical CMakeLists.txt file for a Qt project looks like this:
| | {{CMake/Template/Moved}} |
|
| |
|
| <source lang="cmake">
| | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/doc/tutorials/Qt here]. |
| cmake_minimum_required(VERSION 2.6)
| |
| PROJECT(TestProject)
| |
| | |
| FIND_PACKAGE(Qt4 REQUIRED)
| |
| INCLUDE(${QT_USE_FILE})
| |
| | |
| QT4_WRAP_UI(UISrcs MyWidget.ui)
| |
| QT4_WRAP_CPP(MOCSrcs MyWidget.h)
| |
| | |
| include_directories(${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_BINARY_DIR})
| |
| | |
| ADD_EXECUTABLE(MyProject main.cpp MyWidget.cpp ${MOCSrcs} ${UISrcs})
| |
| TARGET_LINK_LIBRARIES(FileMenu ${QT_LIBRARIES})
| |
| </source>
| |

| However, when you build and run in Windows, you will get a console window that appears along with your GUI program. To fix this, you must do two things. First, add ${QT_QTMAIN_LIBRARY} to your target_link_libraries command. Second, you must specify /SUBSYSTEM:WINDOWS for all build configurations (Release, Debug, etc) that you want to not pop up the console window. An example is below, where when built in release mode, no console will appear:

| <source lang="cmake">

| cmake_minimum_required(VERSION 2.6)
| |
| | |
| PROJECT(FileMenu)
| |
| | |
| FIND_PACKAGE(Qt4 REQUIRED)
| |
| INCLUDE(${QT_USE_FILE})
| |
| | |
| QT4_WRAP_UI(UISrcs MyWidget.ui)
| |
| QT4_WRAP_CPP(MOCSrcs MyWidget.h)
| |
| | |
| include_directories(${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_BINARY_DIR})
| |
| | |
| ADD_EXECUTABLE(TestProject main.cpp MyWidget.cpp ${MOCSrcs} ${UISrcs})
| |
| TARGET_LINK_LIBRARIES(FileMenu ${QT_QTMAIN_LIBRARY} ${QT_LIBRARIES})
| |
| | |
| set_target_properties(FileMenu PROPERTIES LINK_FLAGS_RELEASE "/SUBSYSTEM:WINDOWS")
| |
| | |
| </source>
| |
| | |
| If you want to set this for all build modes, simply use:
| |
| <source lang="cmake">
| |
| set_target_properties(FileMenu PROPERTIES LINK_FLAGS "/SUBSYSTEM:WINDOWS") # works for all build modes
| |
| </source>
