双支持

在项目build.gradle 下定义

ext{
    USE_CMAKE=false
}

在android项目build.gradle定义判断即可

gradle中 宏定义的读取

gradle.中

                cmake {
                    arguments "-DFUCKDEBUG=ON", "-Wno-error=format-security"
}

cmakeList.txt

if (FUCKDEBUG)
    message("---------open log FUCKDEBUG---------------")
    add_definitions(-DFUCKDEBUG)

android.mk

# -DFUCKDEBUG open log

c代码

   #if defined(FUCKDEBUG)
        #pragma message("-----MY LOG_ ON----")
#endif
