important drawback of -k: Say, you have target B depending on A. If A
fails, nothing from B will be compiled, thus hiding programming errors
that will only show up once A is fixed. What needs to be fixed is the
error parser in CTest.

Hi Michael,
I always thought that 'make -k' would try to build as much as possible.
That's also my interpretation from the info pages. Here's the first part
of the third paragraph of Section 9.6 of the make info page:
On these occasions, you should use the `-k' or `--keep-going'
flag.
This tells `make' to continue to consider the other
prerequisites of
the pending targets, remaking them if necessary, before it gives
up and
returns nonzero status.
The way I read this, is that 'make' will try to (re)build as much as
possible of the remaining targets, after an error occurred.
Could it be that nothing of your target B gets (re)built, because CMake
somehow introduces too many dependent targets?
Best regards,
Marcel Loose.
