Options:
[--version]
[--api-version]
Options telling what we are doing:
[--use-gl] use GL
[--use-images] use extra image formats (PNG, JPEG)
[--use-glut] use glut compatibility layer
[--use-forms] use forms compatibility layer
[--use-cairo] use cairo graphics lib
Options telling what information we request:
[--cc] return C compiler used to compile FLTK
[--cxx] return C++ compiler used to compile FLTK
[--optim] return compiler optimization used to compile FLTK
[--cflags] return flags to compile C using FLTK
[--cxxflags] return flags to compile C++ using FLTK
[--ldflags] return flags to link against FLTK
[--ldstaticflags] return flags to link against static FLTK library
even if there are DSOs installed
[--libs] return FLTK libraries full path for dependencies
[--prefix] return FLTK install time --prefix directory
[--includedir] return FLTK install time include directory
Options to compile and link an application:
[-g] compile the program with debugging information
[-Dname[=value]] compile the program with the given define
[--compile program.cxx ..] compile and link the program with optional
.. compiler flags, source files, and libraries
[--link flags and libs] additional linker flags and libraries
.. for --compile, added after all other libs
[--post program] prepare the program for desktop use (macOS)
