By not providing “Findncnn.cmake“ in CMAKE_MODULE_PATH this project has asked CMake to find

as报错: By not providing “Findncnn.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “ncnn”, but
CMake did not find one.

解决

1. 首先要下载导入，文件名称要与cmake文件对应正确
2. 如果还是报这个错误 as问题，只需要删除

set(ncnn_DIR ${
    
    CMAKE_SOURCE_DIR}/ncnn-20221128-android-vulkan/${
    
    ANDROID_ABI}/lib/cmake/ncnn)

grade同步一下，然后再撤销删除grade同步就行。
