This thread is old but I just encountered the same problem on CentOS. 7, etr 0.7.5. After you run autogen.sh, check config.log for missing dependencies for sfml-audio. It turns out that the error was from pkg-config not finding /usr/lib64/pkgconfig/openal.pc for the openal dependency. This fixed it:
export PKG_CONFIG_PATH=/usr/lib64/pkgconfig/
