Running Rust in Docker container with paho_mqtt

[EvilWatermelon]

While trying to build a container I always get the following error:

error: failed to run custom build command for paho-mqtt-sys v0.8.0 (https://github.com/eclipse/paho.mqtt.rust.git?branch=master#8e1f7342)

Caused by:

I'm running this command on an Apple Silicon Chip. Is this a paho_mqtt problem or a CMAKE only problem? It seems for me that mqtt can't find CMAKE.

It needs a native CMake and a cross-compiler to be installed and on the path. The cross-compiler it's expecting sure seems to be aarch64-unknown-linux-gnu from the output above. But it appears to be complaining that it can't find the CMake executable.

RUN apt-get update && apt-get -y install cmake at the beginning in my Dockerfile fixed it.
