Looks like you're getting all the CPU arch options for x86 (the host); I'd simply remove -mtune= from the compiler options, alternatively need to figure out how to apply it to target, not host.

[hmaarrfk]

see: #84 for an alternative.

ppc64le support for qt5 has been merged (via manual build) in #64

[jschueller]

can you rebase/rerender ?

[conda-forge-webservices]

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

I was trying to look for recipes to lint for you, but it appears we have a merge conflict.
Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.
