Wow! That is so nice :)
Please ping me when you are ready for merge! Am I supposed to release a new version afterward to trigger everything in vcpkg (for instance, on conda-forge, if I want a new version to be built, I need to create a new specific release)?

Hi!

The integration is done because ezc3d is integrated in vcpkg. The CI in vcpkg were passed for ezc3d with successfully result:

microsoft/vcpkg#14016

You don't need to do anything. It is already done.

VCPK is not as flexible as conda-forge or pip, each version of VCPKG includes libraries in a specific version and the huge CI process assures that all it is ok. Because of the characteristics of C and C++ it is difficult to design a package manager that lets us specify a specific version of a library. You can check the current version of ezc3d included in vcpkg searching it in the ports folder:

https://github.com/microsoft/vcpkg/tree/master/ports/ezc3d

As you can see the integration is using your release tar.gz package:

https://github.com/microsoft/vcpkg/blob/master/ports/ezc3d/portfile.cmake

You can use ezc3d from vcpkg following the instructions in this PR. Install it using the following command:

vcpkg install ezc3d

It is also possible to specify the architecture, the platform even linkage using triples:

vcpkg install ezc3d:x64-windows

Thank you for support ezc3d library! 😉
