Subject: CMake: enable building FLTK in a subdirectory of another project.

Basically replace CMAKE_XXX_DIR with CMAKE_CURRENT_XXX_DIR where
XXX = SOURCE or BINARY.

Patch proposal by cleanrock, FLTK PR #4:
https://github.com/fltk/test-only/pull/4

Patch modified to fix target dirs for test programs and doxygen docs.
