Я пытаюсь собрать ZXing из его C ++ исходного кода в Android Studio.Но CMake выдает много ошибок, хотя у меня нет большого опыта разработки NDK, и ошибки не достаточно описательны, чтобы понять, не могу понять, что здесь происходит не так.Прямо сейчас я сталкиваюсь со следующей проблемой:
CMake Error at CMakeLists.txt:90 (add_executable):
CMake Error at CMakeLists.txt:91 (add_executable):
CMake Error at CMakeLists.txt:92 (target_link_libraries):
Я пытался прочитать CMake docs , чтобы понять синтаксис команд, они выглядят нормально в CMakeLists.txt (перечислены ниже).
Может кто-нибудь испытал эти нативные вещи, пожалуйста, пролите немного света.
