我在我的代码中包括boost,cpprest和openssl,但它给我的错误像follow在android studio使用ndk我给了所有路径的目录和添加到程序它构建成功,但当我运行它时,它给我以下错误

Build command failed.

请帮我解决这个问题

提前致谢

现在它向我显示错误

set_target_properties( boost_system PROPERTIES IMPORTED_LOCATION
        ${-DMY_BOOST_LIBS_DIR}/${ANDROID_ABI}/libboost_system.so
        )

${-dmy_boost_libs_dir}应该是什么?这个变量的计算值为零,这就是为什么你得到了错误的路径。
