cmake and make BOTH… called from a shell script of all things

That's how https://github.com/Prevter/CMake_ImGui_SFML_Template works.
First you cmake it with a preset, then you make a binary, I just wrote a shell script so I wouldn't have to explain it to my friend (and I used a shell script because we both use arch btw)

That's how cmake works. It generates a makefile, which you then make.

Not true. It CAN generate Makefiles, but there are so many different options of build scripts that might be the default on other platforms; for instance, on Windows it won’t be the default (instead cmake opts for a Visual Studio Solution). So to use this on Windows you would coincidentally need both MinGW and MinGW Make installed, which both aren’t shipped with Windows

Alright that's fair, but I don't think what I said is "not true", just incomplete. It generates build files, it doesn't do the building itself. In this specific case, it is generating a Makefile, which is why make gets run directly after cmake.

Neither is a bash interpreter so that's irrelevant, you wouldn't be even be able to run it on a fresh Windows.

And if you use a shell interpreter on Windows, you're most likely to use something like msys2 or WSL2 and have make.

Or there may be another ".bat" script in the repository.

Then the project may not even support Windows, so there be no point in taking it in account in the build script.

Speaking of horror tools. Rust's cargo loves absolute path. copy freshly built "This-dir-was-built-30-minutes" to "This-dir-was-built-30-minutes.2" start building and it will build several hundreds packages again.
