Как создать файлы libjpeg-turbo.so для разных архитектур ЦП в Ubuntu 16.04?

Я скачал библиотеку libjpeg-turbo из https://github.com/libjpeg-turbo/libjpeg-turbo/ и выполнил следующие команды CMake в Ubuntu 16.04: 

$ cd {path of my libjpeg-turbo library}
$ cmake -G"Unix Makefiles" {path of my libjpeg-turbo library}
$ make

Затем генерируется libjpeg.a, libjpeg.so, libjpeg.so.62, libjpeg.so.62.3.0, libjpegturbo.a, libjpegturbo.so, libjpegturbo.so.0, libjpegturbo.so.0.2.0 и т. Д.

Теперь я пытаюсь сгенерировать файлы libjpeg-turbo.so для разных архитектур ЦП.

Для arm64-v8a: 

$ cd {path of my libjpeg-turbo library}
$ cmake -G"Unix Makefiles" \
      -DANDROID_ABI=arm64-v8a \
      -DANDROID_ARM_MODE=arm \
      -DANDROID_PLATFORM=android-${21} \
      -DANDROID_TOOLCHAIN=${gcc} \
      -DCMAKE_ASM_FLAGS="--target=aarch64-linux-android${21}" \
      -DCMAKE_TOOLCHAIN_FILE=${path of my ndk library}/build/cmake/android.toolchain.cmake \
       {path of my libjpeg-turbo library}

Аналогично, я получаю аналогичный вывод при выполнении для архитектуры armeabi-v7a.

Я не получаю файлы .so для разных архитектур, даже если напечатаны эти три оператора: 

-- Configuring done
-- Generating done
-- Build files have been written to: {path to my libjpeg-turbo library}

Не могли бы вы дать мне знать, как мне добиться генерации файлов libjpeg-turbo.so для архитектур arm64-v8a, armeabi-v7a и armeabi?

Спасибо.
