I did an experiment with a threaded example (to try and reproduce a problem
Sergei Naumov reported) and for building that I simply used a command-line like:
gcc -c example.c -I...all the appropriate include directories
gcc -o example example.o -L.../dll -lplplot -lcsirocsa -lqsastime
under Cygwin. It worked splendidly, with the exception that it does not
reproduce the faulty behaviour, but that is a detail. The reason I bring this
up is that we may need the machinery of CMake to build the entire library with
its - mainly optional - external components and various language bindings, but
once that is done, building a program that uses PLplot is surprisingly simple.
The documentation should include a section on this - we focus so much on
getting PLplot build that we forget about the next step :).
As for having to rely on external libraries: on Windows the run-time libraries
for any program may cause some hassle (suppressing a sigh) - not everything can
be done statically!
Regards,
Arjen
