#.rst:
# FindJNI
# -------
#
# 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. The caller may set variable JAVA_HOME to specify a
# Java installation prefix explicitly.
#
# This module sets the following result 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
