Albrecht Schlosser ec98dc113f CMake: Fix image libraries build if fallback is used
The CMake instructions would use the wrong image libs (png, jpeg, zlib)
if the fallback was active (OPTION_USE_SYSTEM_XXX) was true but the
header files were not present.

This had already been fixed for jpeg but not for the other two libs.
This commit rearranges the logic for all three libs.

Add information about builtin or system libraries to config summary.

README - Fast Light Tool Kit (FLTK) Version 1.4.0

WHAT IS FLTK?

The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
a cross-platform C++ GUI toolkit for UNIX(r)/Linux(r) (X11),
Microsoft(r) Windows(r), and MacOS(r) X. FLTK provides
modern GUI functionality without the bloat and supports 3D
graphics via OpenGL(r) and its built-in GLUT emulation. It
was originally developed by Mr. Bill Spitzak and is
currently maintained by a small group of developers across
the world with a central repository in the US.
