You can pass build options to cmake ... `cmake -DDEBUG=1 -DGLFW_FETCH=0` ... to customise the install, more at [installation](./docs/index.md#available-options).

@ -120,8 +120,6 @@ Q: **_"Are the libraries 1:1 identical?"_**
A: No, there are 100% breaking changes, and changing from miniLibX to MLX42 will not be a simple drop-in replacement. As in their API is slightly different. That was not the idea eitherway, as it would be impossible to fix the problems present in the current miniLibX.
In terms of usage, it's practically identical, while the API Prototypes are slightly different, the usage is roughly the same and the only core difference is the way images are handled.
My suggestion is for students who are using miniLibX to keep using it to finish their project and for new students to prefer the new one or until they reach the next graphical project.
