CMake: improve linking OpenGL3 example programs (#959)
- Remove find_library(LIB_GLEW ...) from 'resources.cmake'
- Use the variable FLTK_GLEW_DIR to "find" a user supplied GLEW library
for OpenGL3 example programs (examples/OpenGL3*.cxx).
Both static and shared libs (DLLs) are supported, but the static
library is preferred to avoid DLL dependencies.
- Define preprocessor macro 'GLEW_STATIC' by CMake compile definitions
if and only if the static glew library (glew32s) was found and linked.
The previous code defined 'GLEW_STATIC' unconditionally in the source
code which led to undefined references if a shared lib (DLL) was used.
