Problem is, not a single file from B will be compiled (if building serial, that is). And I think that such errors are pretty common. Say, somebody changes the implementation of A (not the interface!) and introduces a compilation error there and somebody else messes with B. Although compilation errors from B would still be informative (they don't depend on the implementation of A, only its interface), they don't show up until A is fixed, wasting potentially a lot of time. I agree with you that it is a good thing to abort on first error when doing interactive work, but on a dashboard I prefer to see the whole picture and determine for myself whether a particular error is due to another, earlier error or not. And if you really must, you can do the override by setting the CTEST_BUILD_COMMAND variable to e.g. "/usr/bin/make -k".
