+# - pkg-config module for CMake
+#
+# Defines the following macros:
+#
+#  PKGCONFIG_FOUND(package found)
+#  PKGCONFIG(package includedir libdir linkflags cflags)
+#  PKGCONFIG_VERSION(package version)
+#  PKGCONFIG_DEFINITION(package definition)
+
+# Calling PKGCONFIG_FOUND will fill into the argument the value of the package search's result
+# e.g. PKGCONFIG_FOUND(libart-2.0 LIBART_FOUND)
+#
+# Calling PKGCONFIG_VERSION will fill the desired version into the argument,
+# e.g. PKGCONFIG_VERSION(libart-2.0 LIBART_VERSION)
+# 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
+#
+# Calling PKGCONFIG_VERSION will fill the desired version into the argument,
+# e.g. PKGCONFIG_VERSION(libart-2.0 LIBART_VERSION)
+#
+# Calling PKGCONFIG_DEFINITION will fill the definition (e.g -D_REENTRANT) into the argument,
+# e.g. PKGCONFIG_DEFINITION(libart-2.0 LIBART_DEFINITION)
