Android NDK path variable for “strip” command in CMake build tool chain

by

Thanks @Alex Cohn a lot for pointing out the file android.toolchain.cmake which usually exists at directory ~/Library/Android/sdk/cmake/cmake_version_xxx/android.toolchain.cmake on macOS.

There are many useful Android CMake variables already configured inside, e.g. 

ANDROID_NDK
ANDROID_TOOLCHAIN
ANDROID_ABI
ANDROID_PLATFORM
ANDROID_STL
ANDROID_PIE
ANDROID_CPP_FEATURES
ANDROID_ALLOW_UNDEFINED_SYMBOLS
ANDROID_ARM_MODE
ANDROID_ARM_NEON
ANDROID_DISABLE_NO_EXECUTE
ANDROID_DISABLE_RELRO
ANDROID_DISABLE_FORMAT_STRING_CHECKS
ANDROID_CCACHE

And the one ANDROID_TOOLCHAIN_PREFIX is exactly what I looked for, so my final CMake script comes into below:

add_custom_command(TARGET ${SHARED_LIBRARY_NAME} POST_BUILD
            COMMAND "${ANDROID_TOOLCHAIN_PREFIX}strip" -g -S -d --strip-debug --verbose
            "${DIST_LIBS_DIR}/${LIB_BUILD_TYPE}/${ANDROID_ABI}/lib${SHARED_LIBRARY_NAME}.so"
            COMMENT "Strip debug symbols done on final binary.")

And I don’t need to explicitly pass any additional arguments, i.e. DCMAKE_TOOLCHAIN_FILE=android.toolchain.cmake, from command line to the build process. Because, this file, i.e. android.toolchain.cmake, was already taken into account automatically by Android native build system.
