You don't need to do that; if the pkg-config metafile is on the system, the 
assumption is that the package installation is intact. There's not much point 
in trying to make broken installations work.

Assuming you're using automake, you'll have something like this in your 
Makefile.am:

  AM_CFLAGS = @MODULES_CFLAGS@

... since MODULES is what you called it when you invoked PKG_CHECK_MODULES. 
You can call it anything you like. See pkg-config's man page for more 
information.
