On Arch Linux ARM for Raspberry Pi 2 I get this error:

Was going to close this as a duplicate of #117 as I don't have an Arch setup or time to create one to help fix this.

But your post of ldd shows the linking is omitting lib mmal_vc_client despite it being listed in https://github.com/jacksonliam/mjpg-streamer/blob/master/mjpg-streamer-experimental/plugins/input_raspicam/CMakeLists.txt

I think this issue could be similar to raspberrypi/userland#303

Do you know enough about cmake to try building with the linker flags -Wl --no-as-needed?
