FindGLEW
|
||
--------
|
||
|
||
Find the OpenGL Extension Wrangler Library (GLEW)
|

|
||
Input Variables
|
||
^^^^^^^^^^^^^^^
|
||
|
||
The following variables may be set to influence this module’s behavior:
|
||
|
||
``GLEW_USE_STATIC_LIBS``
|
||
to find and create :prop_tgt:`IMPORTED` target for static linkage.
|
||
|
||
``GLEW_VERBOSE``
|
||
to output a detailed log of this module.
|
||
|
||
Imported Targets
|
||
^^^^^^^^^^^^^^^^
|
||
|
||
This module defines the following :ref:`Imported Targets <Imported Targets>`:
|
||
|
||
|
||
``GLEW::glew``
|
||
The GLEW shared library.
|
||
``GLEW::glew_s``
|
||
The GLEW static library, if ``GLEW_USE_STATIC_LIBS`` is set to ``TRUE``.
|
||
``GLEW::GLEW``
|
||
Duplicates either ``GLEW::glew`` or ``GLEW::glew_s`` based on availability.
|
||
|
||
Result Variables
|
||
^^^^^^^^^^^^^^^^
|
||
|
||
This module defines the following variables:
|
||
|
||
``GLEW_INCLUDE_DIRS``
|
||
include directories for GLEW
|
||
``GLEW_LIBRARIES``
|
||
libraries to link against GLEW
|
||
``GLEW_SHARED_LIBRARIES``
|
||
libraries to link against shared GLEW
|
||
``GLEW_STATIC_LIBRARIES``
|
||
libraries to link against static GLEW
|
||
``GLEW_FOUND``
|
||
true if GLEW has been found and can be used
|
||
``GLEW_VERSION``
|
||
GLEW version
|
||
``GLEW_VERSION_MAJOR``
|
||
GLEW major version
|
||
``GLEW_VERSION_MINOR``
|
||
GLEW minor version
|
||
``GLEW_VERSION_MICRO``
|
||
GLEW micro version
