I agree that this shouldn't be recommended in general, but in our
specific build environment the developers know that they have to run
cmake when they add targets (or even source files, because adding
those are automated too).
The overhead of having to run cmake themselves is a lot less than the
work they would have to do edit a main CMakeLists.txt file and
managing conflicts therein. Most of the time, some options for the new
targets have to be set in cmake anyway.
