Simplify CMake build config for test and demo programs

Browse Source 
Define platform specific library names as CMake variables so they can
be used to build demo programs w/o platform specific instructions.

This includes optional components (e.g. OpenGL) and the MSVC specific
extra object library (call_main) and the fact that we build only one
"monolithic" shared library with MSVC.

Also, enable building FLTK Forms library in CI builds.

# w/o OpenGL as well. These demos show an alternate GUI or a warning

# Note: use "${GLDEMO_LIBS}" for their library parameter
# or "${GLDEMO_SHARED}" to build with shared FLTK libraries
# For building with Visual Studio (MSVC) we also include the special
# object library 'call_main' when linking with the shared libraries.
# Setting the correct library variants as CMake variables may appear
# confusing but simplifies the build instructions below (makes them
# platform independent).
#
# Note that all CMake variables for libraries can be "CMake lists"
# and must therefore be quoted when used in fl_create_example().
