Hello, I have noticed that work is going ahead to introduce CMake, and possibly SCons build systems alongside bjam. Does this not introduce an explosion in required testing combinations, and is this already being addressed? I fully appreciate the attraction of adding CMake, but would like to ensure we do not add too many build systems due to the potentially excessive requirement on library developer to install a plethora of tools, and perform an enormous amount of testing. I wonder if a static analysis tool might be able to help determine the consistency of bjam to the other build systems. Anyhow, I haven't seen much discussion about testing, and if it's not tested it's probably broken! (At least if I've written it!) Regards, Neil Groves
