CMake no CMAKE_C_COMPILER error can be found using Xcode and GLFW

Question

I am trying to follow this guide to get started with OpenGL: http://www.learnopengl.com/#!Getting-started/Creating-a-window, and it requires glfw and CMake to load. I set the downloaded glfw folder as the source folder, and I created another folder inside this folder called assembly, which I then set as the assembly for the binaries, as the tutorial asks. I click "Customize" and choose Xcode as the generator since I'm on a Mac. The problem is that when I try to set up a project, CMake gives me this error:

C compiler id unknown. CMake Error in CMakeLists.txt: 3 (project): CMAKE_C_COMPILER not found.

Incomplete configuration, errors occurred! See also "/Users/standard/Desktop/glfw-3.2.1/build/CMakeFiles/CMakeOutput.log".

See also "/Users/standard/Desktop/glfw-3.2.1/build/CMakeFiles/CMakeError.log".

I have already read this question, but as far as I understand, it does not have what I need: CMake Error at CMakeLists.txt: 30 (project): CMAKE_C_COMPILER could not be found

Thank.

If you installed Xcode, try the following:

sudo xcode-select --reset

Answer 2

Have you installed the Xcode and Xcode command line tools?

xcode-select --install

If you have Xcode command line tools installed, you should no longer receive an error message xcrun.
