Hi Rodrigo, Where is the implementation of the undefined references?
If it is in another source file (other than protpred-Gromacs-NSGA2.c, which seems to be the only one you are compiling) you should add it to the compilation. If it is in another library that is already compiled, you should add it as a linking dependency (using target_link_libraries). Check out http://www.cmake.org/cmake/help/cmake_tutorial.html Cheers!
