我成功交叉编译了 libuv，我正在尝试交叉编译 libwebsockets，但我在使用 buildroot 工具链的 make for arm 中得到以下错误。请指教。

libwebsockets
    cmake .. \
        -DCMAKE_TOOLCHAIN_FILE=~/buildroot/output/host/share/buildroot/toolchainfile.cmake \
        -DLWS_LIBUV_INCLUDE_DIRS=/tmp/cross/include \
        -DLWS_ZLIB_LIBRARIES=/tmp/cross/lib/libuv.so
    make

为什么要手动构建 libwebsockets，而不是使用libwebsockets我们在 Buildroot 中的包？
