FindOpenGLES
|
|
---------------
|
|
|
|
Find the OpenGL ES graphics API.
|
|
|
|
Components
|
|
^^^^^^^^^^
|
|
|
|
The following components are supported:
|
|
|
|
* ``V1`` - OpenGL ES 1 (including emulation on OpenGL ES 2)
|
|
* ``V2`` - OpenGL ES 2
|
|
* ``V3`` - OpenGL ES 3
|
|
* ``V31` - OpenGL ES 3.1 - same as 3 but checking also for gl31.h
|
|
* ``V32` - OpenGL ES 3.2 - same as 3 but checking also for gl32.h
|
|
|
|
If none are specified, the default is ``V2``.
|
|
|
|
Targets
|
|
^^^^^^^
|
|
|
|
If successful, some subset of the following imported targets are created.
|
|
|
|
* ``OpenGLES::OpenGLESv1``
|
|
* ``OpenGLES::OpenGLESv2``
|
|
* ``OpenGLES::OpenGLESv3``
|
|
* ``OpenGLES::OpenGLESv31``
|
|
* ``OpenGLES::OpenGLESv32``
|
|
|
|
Cache variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variable may also be set to assist/control the operation of this module:
|
|
|
|
``OpenGLES_ROOT_DIR``
|
|
The root to search for OpenGLES.
