+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
