set CMAKE_PREFIX_PATH

Not totally sure if this is a good idea or not, but this might make cmake builds more likely to work with less fiddling.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Hmm. Actually, maybe CMAKE_SYSTEM_PREFIX_PATH is more meant for this, and CMAKE_PREFIX_PATH "is intended to be set by the project." And the system prefix path already includes CMAKE_INSTALL_PREFIX which is always set by the build script, but I think that it maybe includes it after the standard system directories. I'll investigate further later.

Something like this sounds like a good idea to me. Though am a bit fuzzy on which CMake paths need to be set ATM.

Also would bump the minor version number once we settle this as this adds functionality without removing any from the toolchain.
