+UsePkgConfig
+------------
+
+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
