The nice things about cget is that even though it uses python(which is mainly for easy distribution), the cget protocol only has a dependency on cmake. So cmake modulues like cmake-get[1] can install cget recipes directly in cmake without needing python installed.
Python is a great solution to the problem as well as being installed on most Linux distros by default.
Chances are devs would need for their other dev tools anyway even not on a Linux machine.
