libdrm is built with bsd makefiles in the OpenBSD xenocara/X11 tree.
http://www.openbsd.org/cgi-bin/cvsweb/xenocara/lib/libdrm/

The *_drm.h headers are shared between userland and the kernel.

ie what Linux calls the 'uapi' headers can be found in
/usr/include/dev/pci/drm/
and the other libdrm headers are currently installed to
/usr/X11R6/include/

The libdrm*.pc pkg-config files reflect this.
