ССЫЛКА СВЯЗИ - SDL (ld: framework не найден SDL)

Попытка построить базовый код SDL на MAC-sierra (версия 10.13.3)

Получение (ld: framework не найден SDL) ОШИБКА.

Вот последняя команда с make VERBOSE = 1 

/usr/bin/g++ -Wall -Wpedantic -Wextra -Wl,-search_paths_first -Wl,- 
headerpad_max_install_names  CMakeFiles/sdl2web.dir/main.cpp.o  -o 
sdl2web  -L/usr/local/lib/ -lGLEW -F/usr/local - 
I/usr/local/include/SDL2/ -framework SDL2 -framework OpenGL

добавив больше деталей: 

cd /usr/local/include/SDL2/ ; ls
SDL.h .. and other header files

pwd
/usr/local/lib
libGLEW.a
libSDL2.a
libSDL2main.a

pwd
/usr/local
SDL2.framework

У вас есть некоторые проблемы с установкой sdl2 на ваш компьютер. На моей машине под управлением MacOS High Sierra (10.13.6) с XCode 9.4.1 я выполнил следующие команды, чтобы заставить его работать: 

$ git clone https://github.com/nickdesaulniers/sdl2web 
Cloned into sdl2web
$ cd sdl2web
$ brew install cmake sdl2
$ cmake .

Чтобы устранить эту проблему на вашем компьютере, попробуйте переустановить cmake и sdl2 с помощью brew. Проверьте вывод pkg-config на правильность флагов: 

$ pkg-config --libs --cflags sdl2
-D_THREAD_SAFE -I/usr/local/include/SDL2 -L/usr/local/lib -lSDL2
