directory that vcpkg builds into with the `HIFI_VCPKG_BASE` environment variable. directory that vcpkg builds into with the `HIFI_VCPKG_BASE` environment variable.
For example, you might set `HIFI_VCPKG_BASE` to `/home/$USER/vcpkg`. For example, you might set `HIFI_VCPKG_BASE` to `/home/$USER/vcpkg`.
By default, vcpkg will build in the system `/tmp` directory. By default, vcpkg will build in the system `/tmp` directory.
If build is intended for packaging or creation of AppImage, VIRCADIA_CPU_ARCHITECTURE
CMake variable needs to be set to architecture specific value.
It defaults to "-march=native -mtune=native", which yields builds optimized for particular
machine, but builds will not work on machines lacking same CPU instructions.
For packaging and AppImage it is recommended to set it to different value, for example "-msse3".
