How to skip dependency with vcpkg?

Question

I am trying to install cgal with vcpkg and getting an error that mpfr dependency can't be installed, because it's site is unavailable. Can I skip this dependency?

I don't know if vcpkg will let you do it, but unless you know cgal well and are certain you don't need mpfr (don't use Epeck in particular), skipping the dependency seems like a bad idea. It would be better to find a way to let it know about alternate locations where you can get mpfr (http://ftp.gnu.org/gnu/mpfr/ and its mirrors, for instance). — Marc Glisse, Dec 07 '19 at 12:45

One can control the dependencies with Build-Depends field in the CONTROL file. In your case ports\cgal\CONTROL

For more information; https://github.com/microsoft/vcpkg/blob/master/docs/maintainers/control-files.md#control-files

However you you remove this dependency most probable you won't manage to build cgal
