Zero to CMake: A beginner's guide to why CMake works
buchanan.onethis article misses a crucial conceptual point of using a higher-level build tool / meta-build tool with this line
cd build && make
cmake --build build/
Yah, absolutely. In the real world that is absolutely the way to go (and I suspect will be managed by your IDE in a lot of cases), but I wanted to show what it means for CMake to be a generator, and Makefiles are the easiest build system to show that with.
yes but nobody cares that it is, because those generated makefiles or ninja files are not user-serviceable, so it might be worth adding a remark to the article (which was very thorough I should emphasise, just that it was missing the reasoning here)
also you might want to consider using
which of course leaves the user in the original place, and as such is a bit more ergonomicmake --directory build/
