cannot open file mpir.lib, while mpir has conflicts with gmp

Issue Details

Hi, I updated my cgal:x64-windows via vcpkg to run obb_example.cpp. And I generated the project using cmake successfully.

I got a link error while debugging it with VS2019. It says that cannot open file mpir.lib, so I tried to install mpir via vcpkg.

However, I found an issue under vcpkg that there are conflicts between gmp and mpir. Here are links:

microsoft/vcpkg#12664 (comment)
microsoft/vcpkg#11756 (comment)

I wonder that is there any chance to use oriented_bounding_box() without mpir or any other way to fix this problem.

Thanks!

At first we used mpir as dependency for cgal in vcpkg, but they changed it for gmp for linux compatibility. This must be the reason for your problem.
My advice would be to vcpkg remove cgal mpir gmp, and then to do:

vcpkg install yasm-tool:x86-windows
vcpkg install cgal

This should solve your problem.
yasm-tool:x86-windows is a dependency for gmp, in case you are wondering.
