My project was building fine with make, until I imported stb, now I get this error

It seems like the program is compiling for x86_64, but the libglfw I've installed from homebrew is for aarch64. How do I get it to compile for aarch64?

CMakelists.txt is using C 20, it's a Vulkan proj (Using custom env vars)

cmake_minimum_required (VERSION 3.12)
project(
    vulkanLearning VERSION 0.1.0
    DESCRIPTION "vulkanLearning"
    LANGUAGES CXX
)

# Specify the C   standard
set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(CMAKE_CXX_EXTENSIONS OFF)
# Set the default path for built executables to the "bin" directory
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/build)
# Set the default path for built libraries to the "lib" directory
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)

add_executable(${PROJECT_NAME} main.cpp)

find_package(Vulkan REQUIRED)
find_package(glfw3 3.3 REQUIRED)

if (VULKAN_FOUND)
    message(STATUS "Found Vulkan, Including and Linking now")
    include_directories(${Vulkan_INCLUDE_DIRS})

CodePudding user response：

It seems as if CMake is building for x86_64 even though your processor runs on arm64. This is influenced by CMAKE_HOST_SYSTEM_PROCESSOR, so that should be arm64.

Setting the CMAKE_OSX_ARCHITECTURE should override that default so that it will build your application for arm64:

set(CMAKE_OSX_ARCHITECTURES "arm64")

That will force clang (or whatever compiler you're using) to compile for arm64.
