# - Find JNI java libraries.
# 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:
#
#  JNI_INCLUDE_DIRS      = the include dirs to use
#  JNI_LIBRARIES         = the libraries to use
#  JNI_FOUND             = TRUE if JNI headers and libraries were found.
#  JAVA_AWT_LIBRARY      = the path to the jawt library
#  JAVA_JVM_LIBRARY      = the path to the jvm library
#  JAVA_INCLUDE_PATH     = the include path to jni.h
#  JAVA_INCLUDE_PATH2    = the include path to jni_md.h
#  JAVA_AWT_INCLUDE_PATH = the include path to jawt.h
#

# Derived from the version included with CMake 2.8.9, with fixes for
# the location that openjdk installs to on Ubuntu 12.10
