fatal error: gfakluge.hpp: No such file or directory

[uveyikk]

Hi,
I am aiming to use c++ api. I downloaded the project and run make successfully. I can use the executable with no problem but couldn't figure out the library. Should I do another things to build the library. And also which path to give while compiling.
g++ -o my_exe my_exe.cpp -L/path/to/gfakluge/ -lgfakluge
For example, if I compile gtest.cpp in the project, which path should I give; build folder, src folder or any other folder?
