The problem you are facing

Why are these git modules used:

[submodule "third_party/extra-cmake-modules"]
	path = third_party/extra-cmake-modules
	url = https://github.com/KDE/extra-cmake-modules.git
[submodule "third_party/syntax-highlighting"]
	path = third_party/syntax-highlighting
	url = https://github.com/KDE/syntax-highlighting.git

?

Why not use packages for these which are part of KDE and are available everywhere?
