well, pkg-config comes with macro PKG_PROG_PKG_CONFIG([MIN-VERSION])
which enables you to enforce a minimal version of pkg-config.

And it comes with macro PKG_CHECK_MODULES, which readily sets
*_CFLAGS and *_LIBS.  Unfortunately, it does not understand the need
of *_CPPFLAGS, which can be set by --cflags-only-I.
