I get some warnings when building in Linux

CMake Warning (dev) at /usr/local/share/cmake-3.31/Modules/FetchContent.cmake:1953 (message):
  Calling FetchContent_Populate(glfw3) is deprecated, call
  FetchContent_MakeAvailable(glfw3) instead.  Policy CMP0169 can be set to
  OLD to allow FetchContent_Populate(glfw3) to be called directly for now,
  but the ability to call it with declared details will be removed completely
  in a future version.
Call Stack (most recent call first):
  Dependencies.cmake:17 (FetchContent_Populate)
  CMakeLists.txt:11 (include)
This warning is for project developers.  Use -Wno-dev to suppress it.

CMake Warning (dev) at /usr/local/share/cmake-3.31/Modules/FindOpenGL.cmake:415 (message):
  Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when
  available.  Run "cmake --help-policy CMP0072" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  FindOpenGL found both a legacy GL library:

    OPENGL_gl_LIBRARY: /usr/lib/x86_64-linux-gnu/libGL.so

  and GLVND libraries for OpenGL and GLX:

    OPENGL_opengl_LIBRARY: /usr/lib/x86_64-linux-gnu/libOpenGL.so
    OPENGL_glx_LIBRARY: /usr/lib/x86_64-linux-gnu/libGLX.so

  OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for
  compatibility with CMake 3.10 and below the legacy GL library will be used.
Call Stack (most recent call first):
  Dependencies.cmake:23 (find_package)
  CMakeLists.txt:11 (include)
This warning is for project developers.  Use -Wno-dev to suppress it.

[bartman]

I was able to get the build (Linux/NixOS/X11) to work with patches #3 and #4,
which are both on my fork: https://github.com/bartman/TheCherno-Architecture

then running

$ cmake -S. -Bbuild -DGLFW_BUILD_WAYLAND=OFF -DGLFW_BUILD_X11=ON -DOpenGL_GL_PREFERENCE=GLVND
$ cmake --build build
$ cd App && ../build/App/App

above is gcc, but clang also worked

$ cmake -S. -Bbuild -DGLFW_BUILD_WAYLAND=OFF -DGLFW_BUILD_X11=ON -DOpenGL_GL_PREFERENCE=GLVND -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
$ cmake --build build
$ cd App && ../build/App/App

I have also working version now:

gh repo clone jotalamp/Architecture -- --recurse-submodules -b linux
