FindGLEW
--------
Find the OpenGL Extension Wrangler Library (GLEW)
Input Variables
^^^^^^^^^^^^^^^
The following variables may be set to influence this modules 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
