I have a fairly new project on github that produces a shared library. Going forward, I would like to use semantic versioning (as described at semver.org) for the shared library major/minor/patch numbers in the file name. The project uses CMake. The CMakeLists.txt file refers to CPACK_PACKAGE_VERSION_MAJOR, CPACK_PACKAGE_VERSION_MINOR and CPACK_PACKAGE_VERSION_PATCH, and sets these to default values if they are not passed
