fd5cd80935 Introduce "Modern CMake" in FLTK
This is a big commit and there are too many changes to list them all.
The main changes are:

- rename all CMake build options to 'FLTK_*'
- export library targets with namespace (prefix) 'fltk::'
- standardize shared library target names with suffix '-shared'
- set public build properties on libraries for consumers
- document library names and aliases in README.CMake.txt
- document changes in "Migrating Code from FLTK 1.3 to 1.4"
- partial backwards compatibility for old user projects

Included but not directly related changes:

- fix Windows (Visual Studio) DLL build
- add CMake function fl_debug_target() to show target properties
- don't build test programs if FLTK is a subproject
- internal: reformat CMake code: remove space before '('

Thanks to Matthias and Manolo for their help, testing, and feeback.

410a01c6db Add CMake compatibility functions and macros
CMake/compatibility.cmake: define functions and macros to be used
  if a particular CMake functionality requires a higher CMake version
  than FLTK's minimum CMake version, see 'cmake_minimum_required(...)'
  in the root CMakeLists.txt.

Note: target_link_directories() is available since CMake 3.13
