How to list all available triplets on remote?
vcpkg triplets are configurations that specify how to build a package for a target environment (OS-architecture-linkage).
The term triplet is a bit confusing, since there can be more to a triplet than these 3 values. For instance target compiler or whether or not the crt is linked dynamically or statically.
The informal way to view the available triplets that ship with vcpkg is:
vcpkg install 7zip --triplet=""
The install command will then list available triplets.
