Notan won't build

[getzen]

I created a new project with cargo and added Notan as a dependency to Cargo.toml, but I get an error message upon trying to build the project. I tried both 0.2.0 and 0.2.1. I have an iMac.

Hi! Notan uses a macro to compile the shaders at build time, this macro uses glsl_to_spriv and it requires to have installed in the system cmake. You can install it using brew install cmake if you have brew in your system, or manually following the steps from https://cmake.org/install/.

This is one of the pain points on notan, I hope to fix it by moving the shader compilation to naga soon.

Let me know if installing cmake works for you.

Thanks for the explanation. I don't have cmake installed, so I'm sure that's the problem. I'm experimenting with different graphics libraries. If I circle back to Notan, I'll install cmake and give it another try.

Nice, rust has some nice libraries, if you're looking for something similar to notan, check https://github.com/not-fl3/egui-miniquad. Have fun!

I'm closing the issue but feel free to reopen if you need it.
