Yes. Typically this means adding or removing one line containing the name of a 
source file from time to time, this is really not much work. You create a new 
source file, edit it, and add its name to the CMakeLists.txt to get it 
compiled. If you don't want to compile it yet, don't add it yet.

I haven't heard anybody complaining about this in the last years.
It is typically really only when setting up cmake for an already existing 
project.
