[CMake] ExternalProject git clone hangs on windows

[Tevet, Avi A]

Just to close the loop: the problem is, I believe, some kind of network problem and not a cmake, git, or ssh misconfiguration problem.  I have found that the clone is very, very slow when using VPN & Samba, even for small repos.  It is intermittently slow when using Samba but not using VPN.  It turns out that what I thought was a hang was actually just an extremely slow git clone, which I found out by letting the MSVC build run for 30 minutes; when I returned, the clone had completed.

Thanks, I hadn’t thought about the SSH problem.  I’ll investigate.

Try clone git project using url from ExternalPoject_add.
Possible git will request something interactively - like add ssh key of remote host or request password.
If so, this was a reason for hang.

As solution - add host keys permanently or change url to https/local clone scheme.
If password used on ssh key - remove it if possible.

HTH,
