Связывание библиотеки CMAKE MAC OSX Проблема: компилируется в Linux, но в Mac

Question

Я пытаюсь скомпилировать мой код с помощью CMake.Но когда я выполняю команду make, я получаю следующую ошибку:

This is the cmake outout I get:

This warning is for project developers.  Use -Wno-dev to suppress it.

Это вывод cmake, который я получаю:

Я пытался запустить код на Linux.Там вроде работает нормально.Я думаю, что это проблема связи между общими библиотеками, которые я создал.

Если вы используете последнюю версию ROOT5 или ROOT6, вместо записи или загрузки FindROOT.cmake, используйте информацию, которую ROOT автоматически генерирует для вас, когда ваша (или ваша система пакетов) ее создает.

В вашей установке ROOT найдите каталог, содержащий ROOTConfig.cmake. Добавьте этот каталог к ​​вашему CMAKE_MODULE_PATH. Затем позвоните find_package(ROOT).

Базовый CMakeLists.txt может выглядеть так:

cmake_minimum_required(VERSION 3.10.2 FATAL_ERROR)

execute_process(COMMAND root-config --prefix 
                COMMAND tr -d \\n
                RESULT_VARIABLE RC_RESULT 
                OUTPUT_VARIABLE ROOT_PREFIX)

list(APPEND CMAKE_MODULE_PATH "${ROOT_PREFIX}/share/root/cmake")
find_package(ROOT)

include(CMakePrintHelpers)
cmake_print_variables(ROOT_FOUND ROOT_LIBRARIES ROOT_INCLUDE_DIRS)

Запуск cmake с результатом:

Вы заметите, что ROOT_FOUND был установлен на TRUE, а ROOT_LIBRARIES и ROOT_INCLUDE_DIRS заполнены. Теперь вы можете использовать эти переменные для настройки компиляции и компоновки.
