Disabling TLS temporarily for downloads

[SimonCahill]

I've noticed an issue with a custom SDK I require for developing software for an embedded Linux device.

Apparently the SDK has been misconfigured, and curl is attempting to read a file which it cannot find:

curl: (77) error setting certificate file: /usr/local/oe-sdk-hardcoded-buildpath/sysroots/x86_64-<company>sdk-linux/etc/ssl/certs/ca-certificates.crt

This means that my project cannot resolve its dependencies:

Is there a way I can tell vcpkg to disable curl's certificate validation?
I'm well aware the situation isn't ideal, but I'd rather not re-do the entire project because of a simple oversight (I didn't check vcpkg's output with the toolchain, rather I focused on building the code for a generic toolchain first).

If any further information is required, please let me know.

Thanks in advance!
