# fl_debug_pkg - a macro to output pkgconfig debugging info
#######################################################################
#
# This macro displays the name and value of some CMake variables
# defined by pkg_check_modules().
#
# Syntax:
#
#   fl_debug_pkg(PREFIX NAME)
#
# Example for package "cairo":
#
#  pkg_check_modules (CAIRO cairo)
#  fl_debug_pkg (CAIRO cairo)
#
# The first command searches for pkg 'cairo' and stores the results
# in CMake variables with prefix 'CAIRO_'.
#
# The second command displays all relevant variables if the package has
# been found, otherwise only 'CAIRO_FOUND' (empty or false).
