.gitexternals parsing

[halfflat]

It looks like the GitExternals script both includes (line 148) the .gitexternals file and also scans it for directory-repository-tag information. However the scanning script will throw a fatal error if there exists a non-comment line in the file (line 153). Doesn't this make the include redundant?

The include is there so that a cmake rerun is triggered when you change the file. The more intuitive way is how it's done for .gitsubprojects, but this I understood to late.
