Yes to calling CMake/etc. No to checking in generated Makefiles. But for your top-level “thing that calls CMake”, try writing a Makefile instead of a shell script. You’ll be surprised at how powerful it is. Make is a dark horse.

I wouldn't be surprised at all, make is great!

My contention is that a build script should ideally be:

sha-bang

clone && cd $cloned_folder

${generate_makefile_with_tool}

make $1

Anything much longer than that can (and usually will) quickly spiral out of control.

Make is great. Unless you're code-golfing, your makefile will be longer than a few lines and a bunch of well-intentioned-gremlins will pop in and bugger the whole thing up. Just seen it too many times.

Edit: in the jenkins case, in a jenkins build shell the clone happens outside build.sh:

(in jenkins shell):

clone && cd clone ./build.sh $(0-1 args)

(inside build.sh): $(generate_makefile_with_tool) make $1
