Tamas Kenez d2e6823451 cmake: install config-module
Installs a config module if CMake verion >= 2.8.12.
The config-module creates the import library targets
built in the project (glew, glew_s, glewmx, glewmx_s)
but in accordance with the FindGLEW module shipped with
CMake, it also creates GLEW::GLEW and GLEW::GLEWMX.

GLEW::GLEW and GLEW::GLEWMX will be simply copies of
glew/glewmx or glew_s/glewmx_s. If both versions are
available they alias the shared versions.

The default behaviour can be changed either when installing
or when using the package:

- Set BUILD_SHARED_LIBS to OFF or ON when building and
  installing GLEW. This controls which libraries
  (shared or static) will be installed (and not which
  will be built).
- Set GLEW_USE_STATIC_LIBS to OFF or ON before calling
  `find_package(GLEW CONFIG REQUIRED)` to force
  the config-module to create GLEW::GLEW and GLEWMX
  as aliases to glew/glewmx or glew_s/glewmx_s

The script ./cmake-testbuild.sh is added to test the
CMake build and config-module. See instructions there.
