I assume that apr-config generates command-line results for the Apache
Runtime Library similar to what pkg-config does in general.  If that
assumption is correct, then to parse the apr-config output you should follow
what is done in FindPkgConfig.cmake (a replacement for UsePkgConfig.cmake in
CMake cvs, but not released yet).  I don't know the implementation details
in FindPkgConfig.cmake, but I do know the pkg_check_modules macro in that
module file delivers nicely parsed (and complete) pkg-config results.
