upgpkg: 4.7.0-2: move to cmake, add webp support, proper makedepends, spdx license
In line with libtiff!3, I am creating a pull request for lib32-libtiff
which does more or less the same thing as that pull request.
- Change to cmake: By changing the build system to CMake, we get rid of gnu autotools, and also generate the cmake targets for libtiff.
-
Add libwebp: By adding libwebp, we can compile libtiff with support for webp tiff photos. libeflate cannot be added as a
lib32-libdeflate
does not exist. - Make licenses SPDX compliant: PKGBUILDs are required to have SPDX compliant licenses now.
- Correct makedepends: I don't know how this slipped the radar, but y'all were not pulling in the 32bit versions for the makedepends.
I have confirmed everything builds in a chroot clean build.
