 # 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

 # Expand {libarch} occurences to java_libarch subdirectory(-ies) and set ${_var}
 macro(java_append_library_directories _var)
     # Determine java arch-specific library subdir
     # Mostly based on openjdk/jdk/make/common/shared/Platform.gmk as of openjdk
     # 1.6.0_18 + icedtea patches. However, it would be much better to base the
     # guess on the first part of the GNU config.guess platform triplet.
