Fixes a bug where wrong CMake variable was checked. Instead of checking
for existence of variable VERSION_STRING the code checked for existence
of variable "value_of(VERSION_STRING)".

Simplify versioning by CMake. Uses git version in the format
"<major>.<minor>.<patch>.r<commits-since-version-tag>.g<hash>(-dirty)?".
