That's not how things work in 1.8.0 and later.

Just build PLIB without any special compile flags:

./configure ; make ; make install

It is now ready to work with GLUT, SDL, FLTK and PW...or
even (with some effort) with your own windowing routines.

Yes - that's true - but if you don't use GLUT, it won't
be included into your program.

Here is what you do:

EITHER:

1) #define PU_USE_GLUT or PU_USE_PW or PU_USE_FLTK or PU_USE_SDL ...to
    explicitly tell PUI which library you want it to use.

...OR...

2) Include the header file for whatever windowing library you are
    using (PW, SDL, FLTK, GLUT, etc) BEFORE you '#include <plib/pu.h>'.
    pu.h will then automatically detect which windowing library you are
    using and set PU_USE_<whatever> appropriately.

...OR...

3) #define PU_USE_NONE    ...and pu.h will assume nothing about your
    windowing library. This is an OK thing to do for every file EXCEPT
    the one that calls puInit().  If you have PU_USE_NONE in the file
    that calls puInit then it may result in some small problems if you want
    to do certain operations for which PUI needs to query the windowing
    library.

...OR...

4) Do none of the above - in which case PUI will assume you are using
    GLUT/freeglut for reverse-compatibility purposes.

Check out the example programs for PU - notably fltk_demo and sdl_example
in the examples/src/pui area and pw_pui in the examples/src/pw area.

If you have your own windowing library (ie not PW, GLUT, SDL or FLTK),
then you can make it work properly with PUI by defining four inline
functions and passing them into 'puSetWindowFuncs'.  Look at (for
example) puGLUT.h to see how this is done.
