Johannes Kauffmann 029e118a4e CMake: Unify usage of pkg_check_modules
According to the CMake documentation, IMPORTED_TARGET should be
specified before the moduleSpec, and after QUIET.

Additionally, double-quote the moduleSpec everywhere, since before, it
was only quoted in some cases.

While this is not required for pkg_check_modules to work, it unifies the
coding style.

Pick-to: 6.5
