FindJNI
|
|
-------
|
|
|
|
Find Java Native Interface (JNI) headers and libraries.
|
|
|
|
JNI enables Java code running in a Java Virtual Machine (JVM) or Dalvik Virtual
|
|
Machine (DVM) on Android to call and be called by native applications and
|
|
libraries written in other languages such as C and 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.
|
|
|
|
.. versionadded:: 3.24
|
|
|
|
Added imported targets, components ``AWT``, ``JVM``, and Android NDK support.
|
|
If no components are specified, the module defaults to an empty components
|
|
list while targeting Android, and all available components otherwise.
|
|
|
|
When using Android NDK, the corresponding package version is reported and a
|
|
specific release can be requested. At Android API level 31 and above, the
|
|
additional ``NativeHelper`` component can be requested. ``NativeHelper`` is
|
|
also exposed as an implicit dependency of the ``JVM`` component (only if this
|
|
does not cause a conflict) which provides a uniform access to JVM functions.
|
|
|
|
Imported Targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
.. versionadded:: 3.24
|
|
|
|
``JNI::JNI``
|
|
Main JNI target, defined only if ``jni.h`` was found.
|
|
|
|
``JNI::AWT``
|
|
Java AWT Native Interface (JAWT) library, defined only if component ``AWT`` was
|
|
found.
|
|
|
|
``JNI::JVM``
|
|
Java Virtual Machine (JVM) library, defined only if component ``JVM`` was found.
|
|
|
|
``JNI::NativeHelper``
|
|
When targeting Android API level 31 and above, the import target will provide
|
|
access to ``libnativehelper.so`` that exposes JVM functions such as
|
|
``JNI_CreateJavaVM``.
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module sets the following result variables:
|
|
|
|
``JNI_INCLUDE_DIRS``
|
|
The include directories to use.
|
|
``JNI_LIBRARIES``
|
|
The libraries to use (JAWT and JVM).
|
|
``JNI_FOUND``
|
|
``TRUE`` if JNI headers and libraries were found.
|
|
``JNI_<component>_FOUND``
|
|
.. versionadded:: 3.24
|
|
|
|
``TRUE`` if ``<component>`` was found.
|
|
``JNI_VERSION``
|
|
Full Android NDK package version (including suffixes such as ``-beta3`` and
|
|
``-rc1``) or undefined otherwise.
|
|
``JNI_VERSION_MAJOR``
|
|
.. versionadded:: 3.24
|
|
|
|
Android NDK major version or undefined otherwise.
|
|
``JNI_VERSION_MINOR``
|
|
.. versionadded:: 3.24
|
|
|
|
Android NDK minor version or undefined otherwise.
|
|
``JNI_VERSION_PATCH``
|
|
.. versionadded:: 3.24
|
|
|
|
Android NDK patch version or undefined otherwise.
|
|
|
|
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 machine-dependant headers ``jni_md.h`` and ``jniport.h``.
|
|
The variable is defined only if ``jni.h`` depends on one of these headers. In
|
|
contrast, Android NDK ``jni.h`` can be typically used standalone.
|
|
``JAVA_AWT_INCLUDE_PATH``
|
|
The include path to ``jawt.h``.
