It's true that you can't use "fltk-config --compile *.cxx" to
compile multi-file projects, but you can still use fltk-config
within the makefile to set flags.
I've just grabbed the following example from an old makefile on
my machine at work:
.o$(EXEEXT):
@ echo Linking $@ ...
@ $(CXX) `fltk-config --use-gl --cxxflags` -o $@ $< \
`fltk-config --use-gl --ldflags`
.c.o:
@ echo Compiling $< ...
@ $(CC) $(CFLAGS) -c $<
.cxx.o:
@ echo Compiling $< ...
@ $(CXX) -Wall `fltk-config --use-gl --cxxflags` -c $<
I have some more readable examples on my machine at home where
I set CFLAGS, CXXFLAGS, etc. at the top of the makefile using
the `fltk-config` trick.
