Summary
Allow compilation without git or when git fails.
Details
This happens when the code is downloaded as source archive. This does not contain the git repository, hence the git version script fails.
Now the version 0.0.0+YEAR.MONTH.DAY is used when we fail to get the version from git.
Motivation and Context
One problem mentioned in #295.
How Has This Been Tested?
Manually by removing the .git directory and adding it back again.
Downloaded the zip archive and did a CMake configure.
