CMake build fails when building a universal binary on MacOS
Summary
This line introduces -mrtm and -mwaitpkg to the compiler flags even when building a universal binary, and this line tries to use the waitpkg functionality, resulting in build errors (see below).
Version
2022.2.0
Environment
- Hardware: Mac Mini Apple M2
- OS name and version: Sequoia 15.4.1
- Compiler version arm64-apple-darwin24.4.0
- CMake generator used: Xcode (Xcode version 16.3)
Observed Behavior
My builds fail due to the introduction of -mrtm and -mwaitpkg (xcode build invocation log):

clang: error: unsupported option '-mrtm' for target 'arm64-apple-macos11.0'
clang: error: unsupported option '-mwaitpkg' for target 'arm64-apple-macos11.0'
Expected Behavior
No build failures in MacOS universal builds.
Steps To Reproduce
Try to build with set(CMAKE_OSX_ARCHITECTURES "x86_64;arm64") in the project's CMakeLists.txt. For reference, here is my full CMakeLists.txt. Apparently this was intended to be fixed in https://github.com/uxlfoundation/oneTBB/issues/910, but the following if-statement passes due to x86_64 being part of CMAKE_OSX_ARCHITECTURES:
if ("${TARGET_ARCHITECTURES}" MATCHES "(x86_64|amd64|AMD64)") # OSX systems are 64-bit only
Note that I have tried commenting out that CMake part that adds the flags, but the build still fails due to this code getting enabled. Manually #undef-ing and #define-ing that macro as 0 fixes the issue, so that check probably needs modification too.
cmake:

No build failures in MacOS universal builds.
Please provide more info about your build environment and cmake options.
I use the Xcode generator (-G Xcode) and I think it's the Xcode generator acting this way. I see that it creates separate build commands for x86_64 and arm64, and they both include -mrtm -mwaitpkg, but only the arm64 version fails, as opposed to your compiler invocation being done once for both architectures.
I use the following CMake options on MacOS:
if(APPLE)
# 10.15 -> std::filesystem::path
# 11.0 -> semaphore.try_acquire
# must be specified before project()
set(CMAKE_OSX_DEPLOYMENT_TARGET "11.0" CACHE STRING "Minimum OS X deployment version")
# this might be needed for homebrew
if(NOT DEFINED CMAKE_OSX_SYSROOT)
execute_process(COMMAND xcrun --show-sdk-path OUTPUT_VARIABLE CMAKE_OSX_SYSROOT OUTPUT_STRIP_TRAILING_WHITESPACE)
endif()
message(STATUS "Using SDK: ${CMAKE_OSX_SYSROOT}")
# universal build
set(CMAKE_OSX_ARCHITECTURES "x86_64;arm64")
set(CMAKE_XCODE_ATTRIBUTE_CLANG_CXX_LANGUAGE_STANDARD "c++23")
set(CMAKE_XCODE_ATTRIBUTE_ONLY_ACTIVE_ARCH "NO")
endif()

As you can see the compiler invocations for x86_64 and arm64 are separated in the Xcode build. The issue seems to be that the compiler is being separately invoked for arm64 only, and it doesn't seem to support the -mrtm -mwaitpkg flags in that case.
