cmake without git access

Apparently cmake did not work properly without access to the git repository. The reason for that is, that cmake is writing the git revision into a header file, to mark output files with the corresponding git revision. This issue needs further investigations.

Success criteria:

• if git access is available the git revision needs be written into the header
• if git is not available a placeholder needs to be written into the header: e.g. git_not_accessible
• in any case cmake should run properly.

@k.kutscher FYI

I just checked cmake without a .git in place and it just worked. Also build info is set up properly:

const char* gitCommitHash()
{
    return "GITDIR-NOTFOUND";
}

const char* gitBranch()
{
    return "GITDIR-NOTFOUND";
}
