Interrupt ctest and get a report?

It would be nice if we can Ctrl+C after make Project/test and see the report for tests that completed so far. There are at least 2 issues

ctest does not produce the Testing/20210716-1434/Test.xml file when interrupted
when we interrupt make, the rule does not finish so we might need some magic like

diff --git project.mk project.mk
index 39debca..692d4e7 100644
--- project.mk
+++ project.mk
