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
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
.. versionadded:: 3.1
|
|
|
|
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
|
|
^^^^^^^^^^^^^^^^
|
|
|
|

|
|
|
|
``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
|
|
|
|
.. versionadded:: 3.7
|
|
Debug and Release variants are found separately.
