Albrecht Schlosser 3fb66056d6 CMake: add missing variable initialization
Although CMake uses previously undefined variables like empty strings
it could happen that variables set in the calling context by other
projects initialized some variables with unexpected values.

Example: FLTK_LIBRARIES could have been initialized by previous
  execution of 'find_package(FLTK ...)' in a project using FLTK

README - Fast Light Tool Kit (FLTK) Version 1.4.0

WHAT IS FLTK?

The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
cross-platform C++ GUI toolkit for UNIX®/Linux® (X11 or
Wayland), Microsoft® Windows®, and macOS®. 
FLTK provides modern GUI functionality without the bloat and 
supports 3D graphics via OpenGL® 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 on GitHub.

For more information see README.txt:
