-# ------------

-# Obsolete pkg-config module for CMake, use FindPkgConfig instead.
-#
-#
-#
-# This module defines the following macro:
-#
-# PKGCONFIG(package includedir libdir linkflags cflags)
-#
-# Calling PKGCONFIG will fill the desired information into the 4 given
-# arguments, e.g. PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR
-# LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT
-# found or the specified software package doesn't exist, the variable
-# will be empty when the function returns, otherwise they will contain
-# the respective information
