Due to GTK's dependencies (header files in a dozen different directories and
many libraries) when using this module you should use:

INCLUDE_DIRECTORIES(${GTK2_INCLUDE_DIRS})
and
TARGET_LINK_LIBRARIES(foo ${GTK2_LIBRARIES})

The module appends all the stuff in two large lists exposed as
GTK2_INCLUDE_DIRS and GTK2_LIBRARIES.
