CMake Error at CMakeLists.txt:32 (find_package):
  Could not find a package configuration file provided by "ncnn" with any of
  the following names:

    ncnnConfig.cmake
    ncnn-config.cmake

  Add the installation prefix of "ncnn" to CMAKE_PREFIX_PATH or set
  "ncnn_DIR" to a directory containing one of the above files.  If "ncnn"
  provides a separate development package or SDK, be sure it has been
  installed.

使用 cmake .. 命令时报错如上，使用 wiki 上的方法安装 ncnn 后还是没解决，（cmake 命令略有不同，-DNCNN_VULKAN=ON 我改为了 OFF 才编译通过）

通过下载 16 Sep 2020 版本的 ncnn 源码编译解决，同时注释掉 CMakeLists.txt 中的 find_package(ncnn REQUIRED HINTS ${NCNN_ROOT_PATH}/lib/cmake)，并在 ADD_EXECUTABLE(LiveFaceReco src/main.cpp) 前面添加 LINK_DIRECTORIES(${CMAKE_CURRENT_LIST_DIR}/include/libs/RaspberryPi4B)。
