acc is now built with cmake instead of the old build script. This was mainly done to fix compilation on Puhti where I had problems linking flex even though it is available. As an added bonus the code is now safer to build since all dependencies are now rigorously tracked by cmake and make, and f.ex. change in the compiler now forces also the whole library to be rebuilt (which is the behaviour we want)
