Do you have a minimal CMakeLists.txt which shows this behaviour? Created attachment 890918 [details]
Test case for the bug
Running the test:
Extract the archive and cd to the directory it created
$> mingw32-cmake .
$> mingw32-make
Thanks for the testcase! I've prepared a new build (against Fedora 19) which should fix the problem (though I didn't fully test it yet): https://koji.fedoraproject.org/koji/taskinfo?taskID=6796108 Could you check if this resolves the issue for you?

Description of problem: Trying to cross-compile a Qt 5 based project for Windows using mingw. The build system of the project is cmake. Linking an executable fails with error: make[2]: *** No rule to make target `/usr/i686-w64-mingw32/sys-root/mingw/lib/libqtmain.a', needed by <the binary name>. Stop. Version-Release number of selected component: 5.2.1-1.fc19 How reproducible: always Steps to Reproduce: 1. have a Qt 5 based project using cmake 2. execute mingw32-cmake 3. execute make Actual results: Linking fails as described above Expected results: Linking should succeed Additional info: The problem seems to be that the build process looks for a file called libqtmain.a in /usr/i686-w64-mingw32/sys-root/mingw/lib directory. But the file provided by the mingw32-qt5-qtbase package is called libqt5main.a which I guess should be used instead. The wrong path comes from the /usr/i686-w64-mingw32/sys-root/mingw/lib/cmake/Qt5Core/Qt5CoreConfigExtras.cmake file on line 76 which says: set(imported_location "${_qt5Core_install_prefix}/lib/libqtmain.a") I changed that line to use the libqt5main.a file and then the linking succeeded.
