CircleCI offers build caching that works well enough, for example. It's not the super advanced stuff that Bazel can do, but you don't need Bazel to do build caching. When the Linux kernel (~27 million LoC) can be compiled from scratch in under a minute on modern machines (30 seconds on some of the beefier machines)... there's clearly a lot of low-hanging fruit in that "hours long" compilation that has nothing to do with build caching. Whether you can get stakeholders to buy into paying down technical debt or not is an unrelated discussion. Sometimes it's easier to sell fancier build systems as the solution instead of better code organization and simplifying overly generic code. C++ code doesn't have to be super slow to compile: https://www.zverovich.net/2017/12/09/improving-compile-times.html https://www.zverovich.net/2017/12/09/improving-compile-times...
