Hi,
I have a problem with parallel build of project with custom command.
Custom command generates two files and depends on generator script. For
optimization purpose first file created only when not exists. This lead
to conflict, even if I "protect" custom command with a custom target and
set explicit dependencies:
> cmake -H. -B_builds
> cmake --build _builds -- -j4 # First build OK
> touch generate.cmake
> cmake --build _builds -- -j4 # Second build. Unexpected `Script run`
several messages
