vcpkg_fixup_pkgconfig uses raw paths in regexes in a couple of places. This causes problems if the path contains characters with special meaning for regexes, e.g. /home/hypothetical-user/Documents/C++, which would fail to compile as it's not a valid regex – causing any invocation of this script to fail if vcpkg is on such a path.
