Allow specification of architecture to install cmake

[benplay2]

grtfmi_install_cmake currently installs cmake for the current architecture.

I request to add an input allowing the user to specify a specific architecture (mac, pc, linux) of archive to download and extract.

Why would that be necessary?

It may be a niche use case, but I populate my directory using Windows, then I share that folder with Linux for a Linux compilation (so I can create an FMU for multiple architectures).

Allowing architecture specification to this install function makes it a little easier to fully setup the folder for all architectures from Windows.
