[CMake] FindQt4 QT_LIBRARIES
Hello,I have looked at FindQt4.cmake module for 2.8.2, but I can't find the code that sets the QT_LIBRARIES variable.Could someone point that out?Regards,___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake

I am now trying to link against QT debug libariries in the RelWithDebInfo cmake
configuation case.
However, it links against the QT release libs when I follow those lines of help
of FindQt4.cmake that describe the typical usage.
This is the cmake code:
FIND_PACKAGE(Qt4 4.5.3 COMPONENTS QtCore QtGui QtOpenGL REQUIRED)
INCLUDE(${QT_USE_FILE})
TARGET_LINK_LIBRARIES(main ${QT_LIBRARIES})
1. when CMAKE_BUILD_TYPE is Release, vs2008 shows the release libs of qt
2. when CMAKE_BUILD_TYPE is Debug, vs2008 shows the debug libs of qt
3. However when CMAKE_BUILD_TYPE is RelWithDebInfo it picks the release qt libs
where I'd want to pick the debug qt libs. Outputting QT_LIBRARIES shows:
optimized;C:/Qt/4.6.0/lib/QtOpenGL4.lib;debug;C:/Qt/4.6.0/lib/QtOpenGLd4.lib;optimized;C:/Qt/4.6.0/lib/QtGui4.lib;debug;C:/Qt/4.6.0/lib/QtGuid4.lib;optimized;C:/Qt/4.6.0/lib/QtCore4.lib;debug;C:/Qt/4.6.0/lib/QtCored4.lib

That will most likely cause your application to crash. You can not mix
debug and release crt. Well at least I spent days figuring out why my
simple qt dialog was crashing for no apparent reason. Then found that
one of the dependencies was causing a mix of debug and release libs.

It does crash currently with release libs for relwithdebingfo config. If I
link against debug libs, it doesn't crash.
The question is: when config is relwithdebingfo, how can I get
TARGET_LINK_LIBRARIES to pick the debug version of the libs from
QT_LIBRARIES?

The question is: when config is relwithdebingfo, how can I get TARGET_LINK_LIBRARIES to pick the debug version of the libs from QT_LIBRARIES? I use Qt release libs with my RelWithDebInfo all the time (2+ years). Since that is the only release build that I use with CMake. I would use depends to verify what .dlls are being used. This one case with a crash I believe I forgot to build 1 lib for RelWithDebInfo and that ended up bringing in Qt debug.

I had other libraries that had the debug version (linked against debug runtime) and that was the culprit (std::string). Now all libs are release with RelWithDebInfo and that works.
