Define version to build with in build system, not recipe

[PokhodenkoSA]

To clarify. This should be >=1.19. Version of numpy to build with should be defined in build system. Now there is no such possibility.

@oleksandr-pavlyk @ZzEeKkAa I believe the original issue was that the conda-recipe meta.yaml should not pin dependency versions rather the version requirements for a dependency should be specified as an environment parameter (e.g. using an environment.yml) when setting up a specific build environment.

What are your thoughts?

PS: My intent here is to clean up some of the old issues that is the reason I am even looking at the ticket.
