# Get forge. We only need headers and aren't actually linking.
# We don't want to use the vcpkg dependency since it is broken in many
# environments - see https://github.com/microsoft/vcpkg/issues/14864. This
# can be relaxed when the issue is fixed. Forge and its dependencies
# are still runtime dependencies, so the user can use the graphics
# library by installing forge and freeimage.
