As another example, Glib puts an architecture-specific header under
libdir and expects you to use pkg-config to make the compiler find it:
$ rpmls glib2-devel | egrep 'glibconfig.h|glib-2.0.pc'
-rw-r--r-- /usr/lib64/glib-2.0/include/glibconfig.h
-rw-r--r-- /usr/lib64/pkgconfig/glib-2.0.pc
-rw-r--r-- /usr/lib/glib-2.0/include/glibconfig.h
-rw-r--r-- /usr/lib/pkgconfig/glib-2.0.pc
$ pkg-config --cflags glib-2.0
-I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include
