Here, where I work, we use prebuilt, and I've done a jam to help us (in attached file). But it bothers me when have to I change the compiler, or other configurations like runtime-link etc, so I prefer use source code.
If there is a way to use source code (even why source code files are smaller than prebuilt files) and once compiled, do not compile again unless explicit, this way would be the best (my opinion); nevertheless, recompiling is not that problem, it's quite fast.
