* Extract prerelease/build information from package semver
Currently we only extract the major.minor.patch identifiers from
the semver label stored in package.json.
This leads to version information in executables incorrectly
reporting a release version is running on prereleases and special builds.
This commit is a quickfix to extract this information and report it
in version strings.
CMake regex parsing is not sophisticated enough to handle the full semver
regex, so we might need to explore other CMake modules if we want to
strictly parse the label.
