I downloaded the latest SFML source from github (
https://github.com/LaurentGomila/SFML) and built the makefile with CMake
and default options. I just tried a small example like you suggested and it
indeed found no problem. I guess the problem s somewhere in the cmake/sfml
combo.
Do you have any experience with CMake so that you may suggest where the
problem may be? I know nothing about CMake.
Thank you.
