Subject: [PATCH] cmake: fix incorrect relative path concatenation (#733)

When a `-DCMAKE_INSTALL_PREFIX` is given, this could result in paths like:

    /path/to/prefix//path/to/prefix/lib/cmake/glog/glog-modules.cmake

which was incorrect.

If a relative `DESTINATION` is given, it's assumed to be relative to the install prefix.
