if( ${ANDROID_ABI} MATCHES "armeabi-v7a" )
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g -mfloat-abi=softfp -mfpu=neon -march=armv7-a -mtune=cortex-a8")
message(${ANDROID_ABI},当前启用neon设置)
endif(${ANDROID_ABI} MATCHES "armeabi-v7a")
7.设置编译参数
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DUSE_JNI_LOG=1")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DANDROID_STL=gnustl_static")
