Hi David, I vaguely remembered that limitation of 'make' as well, but I couldn't find any relevant pointers on this, and colleagues questioned this alleged limitation. Therefore I thought it might be a limitation of CMake, or maybe I should say: the combination of CMake and make. Anyway, my response was also to do two separate 'make' calls, one for each target.
