Could you please send this CMake file to the upstream as a new pull request there? Even if not accepted, still can have feedback from the author.

[maksim-petukhov]

I'll try to find time to do this (this CMake can't be sent as is). Is it a blocker for approving this PR?

We try to avoid patching in CCI as may differ from the original behavior from the upstream and because CCI will become the maintainer of a non-official patch. It's documented here: https://github.com/conan-io/conan-center-index/blob/master/docs/adding_packages/sources_and_patches.md#policy-about-patching

The libntv2 already offer a Makefile, much more limited, but with some build support at least. So that's why I asking to send to the upstream first, so in case they accept, we will no longer need to patch it here. Or at least, they can provide some feedback.
