Thanks ofor the hint. I didn't know run-output and time. Are these commands documented?

This allows me to get the time but in order to get again the time I need to force to build all with -a. I would like to build all the executables targets, and then be able to run performance tests several times.

BTW, I need to pass some args when running the program. I do this now as
