老外真辛苦：
I upgraded my project code from Qt4 to Qt5. It uses CMake. The conversion got well except for one line of Cmake commands related to Qt. I can’t find in current documentation, like
How to link with QtMain from CMake (with Qt5)?
It is the only missing bit to convert my project. Can someone point me to a doc explaining this or explain how to do it with Qt5? My Qt4 code worked correctly but the macro I can't find the Cmake macro for Qt5.
EDIT> Here is the CMake file I have at the moment:https://bitbucket.org/klaim/aos_qt5/src/593c195c4c6889f6968d68fca018ef425783a063/tools/aosdesigner/CMakeLists.txt?at=wip_qt5
All qt5 necessary CMake macros have been set correctly I belive, the only thing that don't work is the linking to QtMain that do nothing, as expected since there should be a Qt5 specific way of doing it that I don't find in the Qt5 documentation.
You can browse the file history to see how it was working with Qt4.
EDIT : Thanks to Archi comment (see below), simply add
target_link_libraries(<your_app> Qt5::WinMain)
or
target_link_libraries(<your_app> ${Qt5Core_QTMAIN_LIBRARIES})
in your application's CMakeLists.txt. Both syntaxes worked for me.
