Thanks for your PR.

I would prefer the use of a default environment variable that we can update on build time, rather than "uname" to get the system architecture.

This will result in a predictable builds, especially in automated CI builds.

Hi @abousselmi ,

Thanks for your comment!
Do you mean to use Docker env var TARGETPLATFORM or TARGETARC(https://docs.docker.com/reference/dockerfile/#automatic-platform-args-in-the-global-scope)?

BR,
Andrei

Hi @xandlom

TARGETARCH might work ! The only problem is that it's supported by BuildKit, not sure if other build engines like Kaniko support it..

I think you can simply specify something like TARGET_ARCH and set it to x86_64. Then it can be updated using --build-arg.

Cheers,

As explained previously, we can add

ARG TARGET_ARCH=x86_64

and replace

by

https://github.com/Kitware/CMake/releases/download/v3.22.1/cmake-3.22.1-linux-${TARGET_ARCH}.sh -O cmake_installer.sh

which can be updated later on using --build-arg
