Albrecht Schlosser 720b84ef9d CMake: refactor and reformat CMake files
- raise minimum CMake version from 2.6.3 to 3.2.3 (Jun 01, 2015)
- indent all CMake files according to the CMP (2 col.)
- refactor FLTK version number definitions and usage
- unify CMake and autoconf/configure variable names:
  - FL_VERSION -> FLTK_VERSION
  - FL_MAJOR_VERSION -> FLTK_VERSION_MAJOR
  - etc. for _MINOR_ and _PATCH_, respectively
  - note: this does not affect FL_VERSION etc. in source code
- generate "export headers" for all libraries (experimental: OFF)
- port some forgotten goodies from branch-1.3 to master
- merge and improve macro 'create_example' (WIP)
- remove "temporary" options and code for older CMake versions
- include and use 'GenerateExportHeader' (experimental, WIP: OFF)
  - note: created header files are not yet used
- build only *one* DLL with Visual Studio (tested, works)
  - similar to the bundled IDE projects in 1.3.x
- add some dynamically linked test/demo programs ('*-shared')
  if shared libraries are built (WIP)
- split 'macros.cmake': use one file per macro

# fl_debug_var - a macro to output debugging info
#######################################################################
#
# This macro displays the name and value of a CMake variable.
# The variable name is expanded with spaces to be (at least)
# <min_len> (currently 24) characters wide for better readability.
# VARNAME must be a string literal, e.g. WIN32 or "WIN32".
#
# Syntax:
# fl_debug_var(VARNAME)
#
# Example:
# fl_debug_var(WIN32)
# fl_debug_var("UNIX")
#
#######################################################################
