$ cmake -Wno-dev .

The library is placed at wrong path, this should be the pkg author's missing, please contact with the author for helping.
You can install ncnn manually with CMake, using "install" target.

I only install it with cmake's install target, and then this problem occurs.

[akemimadoka]

Can you provide your build command, install log and if possible, the path structure of installed target?
