I somehow miss what you have in mind.

What emacs 24.2 has is an own copy (why?) of the PKG_CHECK_MODULES macro
that is shipped as part of pkg-config, and that is today the de-facto 
standard for library detection and library specific LIBS and CFLAGS
setting in open source software.

Anything I miss here?
