FindJNI
|
|
-------
|
|
|
|
Find Java Native Interface (JNI) libraries.
|
|
|
|
JNI enables Java code running in a Java Virtual Machine (JVM) to call
|
|
and be called by native applications and libraries written in other
|
|
languages such as C, C++.
|
|
|
|
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.
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module sets the following result variables:
|
|
|
|
``JNI_INCLUDE_DIRS``
|
|
the include dirs to use
|
|
``JNI_LIBRARIES``
|
|
the libraries to use (JAWT and JVM)
|
|
``JNI_FOUND``
|
|
TRUE if JNI headers and libraries were found.
|
|
|
|
Cache Variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variables are also available to set or use:
|
|
|
|
``JAVA_AWT_LIBRARY``
|
|
the path to the Java AWT Native Interface (JAWT) library
|
|
``JAVA_JVM_LIBRARY``
|
|
the path to the Java Virtual Machine (JVM) library
|
|
``JAVA_INCLUDE_PATH``
|
|
the include path to jni.h
|
|
``JAVA_INCLUDE_PATH2``
|
|
the include path to jni_md.h and jniport.h
|
|
``JAVA_AWT_INCLUDE_PATH``
|
|
the include path to jawt.h
|
|
