License inconsistency betweent the LICENSE file and the setup.cfg metadata

[mattip]

The LICENSE says Apache2, the setup.cfg says GPL2. The underlying libheif is LGPL3. Found this by digging into the list of projects from this comment on numpy/numpy#24138. Did I read things right here?

x265 HEVC encoder has GPL2.
libheif as you say has LGPL3.
Sources of the pillow_heif is under Apache2.

GPL2 is license for binary wheels, as x265 binaries are in the wheels.

P.S.: I have a solution for that in mind, as latest libheif supports plugins, need to check idea on the musl based OS, if ok LICENSE will be Apache2(source)/LGPL3(wheels) for pillow_heif for next releases.

I think Apache2 and GPL2 are incompatible licenses, from the middle of https://www.apache.org/licenses/GPL-compatibility.html:

Despite our best efforts, the FSF has never considered the Apache License to be compatible with GPL version 2, citing the patent termination and indemnification provisions as restrictions not present in the older GPL license. The Apache Software Foundation believes that you should always try to obey the constraints expressed by the copyright holder when redistributing their work.

I will change the license to BSD 3-Clause from the next release.
Thank you for pointing it out.
