Vulkan

[kevinzezel]

Hi,

I installed ncnn with vulkan on the raspberry pi 4B 8Gb correctly and I'm running the ncnn examples successfully on vulkan. But I'm not knowing how to correctly configure my CMakeLists.txt file to reference the glslang library.

Error:

Obs: Everything runs perfect with Ncnn without Vulkan
