Hi Pierre-Julien, Are you sure it's rebuilding? CMake (or 'make' actually), prints a lot of messages "Built target ..." even if no compilation was needed. However, if you also see messages like "Building ..." then it is actually rebuilding.
Without an example of the output of your build, it is hard to judge what, if anything, is going wrong. Best regards, Marcel Loose.
