CMake wants a relative path for CMAKE_INSTALL_*DIR, an absolute path
breaks cross-compilation. This fact is documented in the following
ticket: https://cmake.org/Bug/view.php?id=14367
$sysconfdir and $localstatedir are not relative to $prefix, so they are
still set as absolute paths. With his change ${PROJECT}Targets.cmake
that are generated by cmakes "export" function will contain relative
paths instead of absolute ones.
