Hi,
I've noticed that Visual Studio doesn't run custom commands added with
add_custom_command in parallel. This means running moc and uic is slow
on Windows. Is there something that can be done about this?
No, I don't think so, VS does not work like that. It only does target
parallelism. Not per-command parallelism. It never has don that... You
can get the compiler to do it with the /MP flag, but not custom
commands, unless the command itself supported it.

Couldn't cmake provide a generic wrapper around commands to allow
multiple to be run, e.g
cmake --run --command "moc -o moc_foo.cc foo.h" --command "moc -o
moc_bar.cc bar.h"
or the following where moc_script.txt contains one line per command
cmake --run --command-script moc_script.txt
With such cmake support you could use add_custom_command with multiple
outputs to get things like moc and uic generation done in parallel,
couldn't it?
Best regards,
Thomas
