Subject: [PATCH] CMake/Windows/MSVC: add DLL path as target property

This modifies the debug environment so demo programs linked to FLTK
DLL's can be debugged w/o copying FLTK DLL's to the build folders
of the demo programs.

This is work in progress and may be improved in a future commit but
it works as it is now for all demo programs.
