The main difficulty with C/C++ is making the build steps "hermetics". The build system is frequently unaware of what files the preprocessor will touch/lookup before hands. Build systems like Bazel are providing some way to ensure some level of isolation that provides correctness guarantees. It also provide an easy way to statically build a superset of the files needed for each step of the build, allowing to integrate with a distributed service. Some related documentation/discussions can be found starting from https://docs.bazel.build/versions/master/remote-execution.html https://docs.bazel.build/versions/master/remote-execution.ht...
