+# - 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
+#
