Description

Cmake cache generation fails while generating on x86-linux with vcpkg

heres my condensed CMakeUserPresets.json

Everything seems to run smoothly on x64, with no issues. It might be a problem with vcpkg not supporting x86-linux officially, however I see no reason why that would break anything.

Example/How to Reproduce

1. setup vcpkg with x86, and VCPKG_TARGET_TRIPLET as x86-linux
2. configure cmake, in my case with CMakeUserPresets.json as cmake --preset=linux

Possible Fix

No response

Where did you get it from?

vcpkg
