We used to have something that removed many implicit rules. I think that got lost in some version of CMake, it is hard to test... I did find that there is a command line option to gmake, -r that turns off implicit rules. I am seeing a speed up with gmake -r. Would it work to turn off all implicit rules instead of the .PHONY stuff? CMake does not use any implicit rules anyway. I think the only way to turn them off is to redefine them as empty rules. This works for all make, and not just gmake. I am trying to figure out what implicit rules need to be turned off and how to turn them off. Any ideas?
I played around with make -d and -p and found that the .SUFFIXES rule that was supposed to be removing the implicit rules for gmake was not working for everything. SCCS and RCS were being checked for a bunch of stuff. Anyway, try this and see if it improves the issue you were seeing:
