Compilation fails with boost 1.84.0 on macos

I am using magnum with my project as a subdirectory.

If the boost version is 1.84 it fails in compilation If the boost version is 1.73.0 it works fine.

temporary solution is to move

find_package(Boost) include_directories(${Boost_INCLUDE_DIRS})

below

add_subdirectory(corrade EXCLUDE_FROM_ALL) add_subdirectory(magnum EXCLUDE_FROM_ALL)

cmake_minimum_required(VERSION 3.26)

project(TEST)

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

set(CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/modules/" ${CMAKE_MODULE_PATH})

find_package(Boost)
include_directories(${Boost_INCLUDE_DIRS})
# Add Corrade as a subproject
add_subdirectory(corrade EXCLUDE_FROM_ALL)
add_subdirectory(magnum EXCLUDE_FROM_ALL)
message(${Boost_FOUND})
message(${Boost_INCLUDE_DIR})
message(${Boost_VERSION_STRING})
find_package(Magnum REQUIRED)

# set_directory_properties(PROPERTIES CORRADE_USE_PEDANTIC_FLAGS ON)

add_subdirectory(src)
