build stratagus make fatal error: mdns.h

[Jarod42]

Do you have stratagus/third-party/mdns/mdns.h ?
I think submodules are missing.
git submodule update --init might help.

I just updated the wiki to add --recurse-submodules when cloning to avoid that step.

[johndoe71rus]

yes, submodules are missing.
now cmake very cool

[Jarod42]

Someone got similar issue previously, evil MACRO None defined in a third library :-(

CI is currently broken, so I cannot rename our enum value None to avoid conflict with that evil MACRO.

[Jarod42]

Should be fixed with #558

[johndoe71rus]

yes, fixed. build wargus and stratagus
