Subject: [PATCH] Fix a bug from pkg-config. pkg-config would ignore flags like
 '-I/usr/include' in cflags; as ${prefix}_INCLUDE_DIRS is initialized from
 `pkg-config --cflags-only-I ${pkgname}`, it would be empty as only
 -I/usr/include in cflags. However, under this situation, cmake would still
 mark ${prefix}_FOUND as true, and without these global-visible includes no
 compilation issues arise; thus, this commit turns off detect of
 Libxc_INCLUDE_DIRS, and use Libxc_found instead.
