As mentioned in https://github.com/TokTok/c-toxcore/issues/359#issuecomment-270710463 the current CMake build does not generate version symlinks for library .so files. This is because the version is not specified for library targets. See - https://cmake.org/cmake/help/v3.0/prop_tgt/SOVERSION.html#prop_tgt:SOVERSION - https://cmake.org/cmake/help/v3.0/prop_tgt/VERSION.html#prop_tgt:VERSION Use PROJECT_VERSION_MAJOR and MINOR for SOVERSION because api may break from 0.1 to 0.2 in the 0.x release cycle.
