- 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
