Best way to deal with cmake find_package?

[xumykargo]

Hi,

I am building some external project depending on opencv. The project uses cmake find_package to find opencv. I have built opencv from source with bazel and it's available as a target, but what's the best way to make find_package find that target?

Also on my machine there's a system installed opencv, and how do I ensure hermetic build by preventing cmake to find the system opencv? Does sandbox work here? Asking because the cmake rule seems to use the system opencv.

Thanks!

Have you tried adding opencv in bazel and then adding deps = ["@opencv"] to the cmake rule?
