A modern programming language that makes developers happier.

kotlinlang

it looks so:
```elect@elect-NUC8i5BEK:~/CLionProjects/kotlin-native-opengl-tutorial$ ls /usr/include/GL/
glcorearb.h   glext.h       gl_mangle.h   glu_mangle.h  glxext.h      glxint.h      glxmd.h       glxtokens.h   wglew.h       
glew.h        gl.h          glu.h         glxew.h       glx.h         glx_mangle.h  glxproto.h    internal/  ```

Error message says it cannot find `GL/glew.h`
But if you added `compilerOpts.linux = -I/usr/include` to cglew.def - it should be available. Maybe you installed from different user account?

yep, indeed, I erroneously added `compilerOpts.linux = -I/usr/include -I/usr/local/include` in `cglfw.def` instead `cglew.def`
