#
# This module finds if Java is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#
#  JAVA_AWT_LIB_PATH     = the path to where the jawt library is
#  JAVA_INCLUDE_PATH     = the path to where jni.h can be found
#  JAVA_AWT_INCLUDE_PATH = the path to where jni.h can be found
