CMake build issues on Apple M2 Pro running Ventura 13.5 macOS

[WizzerWorks]

I attempted to build using CMake on a Apple M2 Pro laptop running Ventura 13.5 macOS.

I see the following error from build directory

% cmake .. CMake Warning (dev) at CMakeLists.txt:1 (project): cmake_minimum_required() should be called prior to this top-level project() call. Please see the cmake-commands(7) manual for usage documentation of both commands. This warning is for project developers. Use -Wno-dev to suppress it.

Could not find a package configuration file provided by "glm" with any of the following names:

glmConfig.cmake
glm-config.cmake

Add the installation prefix of "glm" to CMAKE_PREFIX_PATH or set "glm_DIR" to a directory containing one of the above files. If "glm" provides a separate development package or SDK, be sure it has been installed.

The same issue with Mac M1 14.4.1 with cmake 3.27.3

CMAKE is the right tool to use but nearly all my development used Xcode as a build platform, so I’m not really familiar with any issues with CMAKE.MikeSent from my iPhoneOn Mar 28, 2024, at 7:05 AM, Nicolas Roduit @.***> wrote: The same issue with Mac M1 14.4.1 with cmake 3.27.3

CMakeLists.txt shows dependencies:

find_package(glm REQUIRED) find_package(OpenGL REQUIRED)

OpenGL is not on my M2 Ventura 13.5 platform. If this is a port on top of Metal, then I would not expect OpenGL to be required at all. If it is for header files, then the header file should be provided separately (not from package).

Maybe open gl is needed for gli_context.h?MikeSent from my iPhoneOn Mar 29, 2024, at 12:52 PM, Mark Millard @.***> wrote: CMakeLists.txt shows dependencies: find_package(glm REQUIRED) find_package(OpenGL REQUIRED) OpenGL is not on my M2 Ventura 13.5 platform.

I was able to get MGL to build through a combination of CMake and Xcode. I've forked MGL to look at using it for building Coin on Apple Silicon. I created a wiki in forked MGL. Cmake was used for externals and Xcode for MGL and GLFW.

I tried to rewrite the build system to use CMake + FetchContent instead of Xcode + Shell scripts: https://github.com/julcst/MGL.git

It builds and compiles successfully in VSCode without Errors but some of the tests are unfortunately broken, especially the texture tests and the uniform tests. If anyone has an idea why that could be I would greatly appreciate it. Maybe this occurs because I deleted a lot of files that seemed unnecessary:

• Unused/**
• enum_parser/**
• spec_parser/**

I also replaced all the explicit external dependencies with FetchContent calls that automatically fetch them from their respective repositories. Thus I deleted:

• MGL/spirv_cross_c.cpp (Is this different from the imported spirv_cross_c.cpp?)
• MGL.xcodeproject/**
• Makefile
• SPIRV-Cross
• SPIRV-Headers
• external/**.sh
