cargo is not a compiler, it's a build system. The difference between build systems and compilers is that compilers implement language specs, and build systems do whatever they want. That's the problem with having multiple build systems. The fact that there is so much heterogeneity in C/C++ land means I spend way too much time trying to build things. When things are standardized, I don't have to think much about builds. They just work. If build systems were made to interoperate (e.g. by having a common spec, or by implementing the same behavior), then we could have competing build systems without the fragmentation.
