  > I feel like Bazel is much more convincing _after it's working_, cuz you really do get much faster builds. I have to call bullshit on this claim. CMake is at its hear a build system generator. It offers a high-level abstraction to define software projects, and it uses that abstraction to generate the actual build system. It can generate makefiles, but also Ninja, Xcode, visual studio, and even msbuild projects. What actually does the build is not CMake, but make, msbuild, ninja, Xcode, or visual studio. Not CMake. You run CMake once to generate the build project, and when you actually want to build the project you only call ninja or make etc. To top that off, some of these build systems support build cache systems such as sccache or ccache. Plugging in one of these tools can easily drop build times to a fraction of the time. Literally. I had C++ projects which used CMake whose build time of a complete rebuild dropped to 15% of it's original time.
