# - pkg-config module for CMake
# Defines the following macros:
#   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
