CMake's --install --strip command will result in calling ${CMAKE_STRIP}
after installation.
On the build machines we have multiple compilers, and ${CMAKE_STRIP} will
have a valid program e.g. C:/strawberry/c/bin/strip.exe
This will change the MSVC binaries to have a MinGW linker version flag,
which confuses Qt Creator when setting up a MSVC Kit.
