You must compile your ncnn with glslang support
cmake -DCMAKE_BUILD_TYPE=Release -DNCNN_VULKAN=ON -DNCNN_SYSTEM_GLSLANG=ON -DNCNN_BUILD_EXAMPLES=ON ..
doesn't forget to clone the libncnn repository with --recursive option

git clone https://github.com/Tencent/ncnn.git --recursive

[thinhemb]

you can setup your ncnn android by
cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK_LATEST_HOME/build/cmake/android.toolchain.cmake -DANDROID_ABI="armeabi-v7a" -DANDROID_ARM_NEON=ON -DANDROID_PLATFORM=android-24 -DNCNN_VULKAN=ON -DNCNN_SHARED_LIB=ON -DNCNN_ENABLE_LTO=OFF ..
