cmake fail at Performing download step (git clone) for 'html'

[hackob]

cmake fails when executing the step where it clones the html repository since it cannot connect to github:

=> => # Cloning into 'html'...                                                              
=> => # fatal: unable to connect to github.com:                                             
=> => # github.com[0: 140.82.114.3]: errno=Connection timed out                             
=> => # Cloning into 'html'...

Tried the following options, same result:

GIT_CLONE=https:
GIT_CLONE=git:
