Trying to build simple application generated in Qt Creator using template "Qt Widgets Application" with choosen CMake build system fails at link stage when using Qt being statically cross-compiled for mingw.
It outputs lots of "undefined reference" errors.
The reason is improperly generated Qt5<MODULE>Config.cmake files containing wrong paths to modules .prl files, where CMAKE_PRL_FILE_LOCATION_* values populated by qtbase/mkspecs/features/create_cmake.prf contains prefix "lib" in base filename.
Fixing their definitions for mingw platform resolves issue. Not sure about other platfrom variants, which may be broken too.
