This is interesting as I have come across something that sounds related but
might not be. Inside of QtCreator my projects are setup to call “cmake –build
${build_dir} –target all”. After updating to Xcode 10.1 from Xcode 9.4.x when I
stop my build inside of QtCreator the cmake process itself is stopped BUT the
actual compilers (clang in my case) keep going. I have to open a terminal and
“killall clang” to get everything to stop. I never had a problem until I
updated to Xcode 10.1. This is with CMake 3.13.0 and macOS 10.13.6. Again,
maybe related, maybe not.

Subject: Re: [CMake] CMake GUI "Stop" button does not halt exec_process
I don't follow. None of this looks like I can press stop in CMake and have the
process die. I'm not making any additional children, just execute_process in
CMak (so 1 child that never gets killed).

Hi,
killing everything might be problematic in some cases: MSVC uses some shared
processes to write PDB files. Killing that will make an unrelated other build
fail. That was real fun to find out when Jenkins was cleaning up. So kill your
children but don't be too pedantic.

In case it helps, Box Backup uses Windows Job Objects to ensure that any
daemons started during a test will automatically be killed when the test
process exits (if not stopped cleanly beforehand):

On Linux you can use prctl(PR_SET_PDEATHSIG, SIGKILL) in the child process
(between fork() and exec()) to achieve this.

Pressing "STOP" in the CMake GUI interface halts CMake itself but does not stop
any execute_process that is going on at the time. This makes it hang until the
process finishes, since no interrupt is sent......
Aggravating when you're using an exterior script (e.g. a .exe or .py) that e.g.
handles package maintenance. Would hang up for the entire duration of ~40
minutes unless you force kill that sub process.
I think force-killing CMake GUI also won't forward the kill to the
exec_process, orphaning it.....>.<
Let me know any suggestions or possible fixes
