Currently learning openGL in rust and decided to add e-gui, to make immediate changes. Decided to use this crate: https://crates.io/crates/egui_glfw_gl/0.13.1

After adding it to Cargo.toml can't build or run.

PS opengl_t_2> cargo run
   Compiling glfw-sys v3.3.5
error: failed to run custom build command for `glfw-sys v3.3.5`

Caused by:
  process didn't exit successfully: `opengl_t_2\target\debug\build\glfw-sys-d98b92fc73a7f019\build-script-build` (exit code: 101)

Cargo.toml:

[dependencies]
cgmath = "0.16.1"
gl = "0.10.0"
image = "0.19.0"
tobj = "0.1.6"
num = "0.2.0"
rand = "0.5.5"
egui = "0.17.0"
egui_glfw_gl = "0.13.1"

[dependencies.glfw]
git = "https://github.com/bjz/glfw-rs.git"
default-features = false

Without egui-glfw, everything builds and I have a functional 3d scene.

File structure

I apologize, if this is a stupid question, but I have already tried everything.

CMAKE = Some("C:\\Program Files\\CMake\\bin\\")

For whatever reason, your CMAKE environmental variable is pointing to a directory rather than the cmake.exe binary.

Make sure that you have cmake installed, and edit your CMAKE envvar to point to it. Or remove it, if cmake is in your PATH.

  • So if I understand correctly, I should either have a CMAKE variable pointing to the .exe or having the path to the .exe in the PATH variable? Because calling 'cmake' from the terminal works. – Vasily Levitskiy Jul 02 '22 at 22:04
