How can the platform keyword in vcpkg.json be made to recognize operating systems other than common ones like Windows, Linux, and Android?

[AlexOct]

I added a new operating system called "myos" in the triplet, and the basic project build is working. However, when introducing third-party libraries and setting the platform keyword to "myos" in vcpkg.json, vcpkg does not recognize the required libraries and prompts that the keyword is not available. Is there a way to make the platform keyword in vcpkg.json recognize "myos"?

I think you can set VCPKG_DEP_INFO_OVERRIDE_VARS in your triplet. So
set(VCPKG_DEP_INFO_OVERRIDE_VARS "myos")

But afaik you have to set set(VCPKG_DEP_INFO_OVERRIDE_VARS "!myos") in the others triplet or you get an error that the identifier myos is not known.

Is there any way to set it once in one place and use it elsewhere, or else it will require too many modifications?
