This commit adds an image transformation library called zimg.
There are a number of patches applied. One is from upstream and supports
building on GCC-15, the others are autotools patches to allow installing
various components useful for verifying the library is working on the
target, which are not usually installed by the upstream project.
Note that while this version of zimg claims to support C++11 upwards,
upstream is moving towards only supporting C++17 upwards in the master
branch.
This has been tested on a Raspberry Pi 4 and a Raspberry Pi 5, and on
x86_64 (run in a chroot).

Thanks for this patch! It overall looks good, and I only have a few
comments see below.

For this one, and the other 2 patches that you marked as not
upstreamable, could you take the same approach as your patch
0004-Add-option-to-install-tests.patch, which is to add a ./configure
option to enable/disable installation of the test application, of the
examples. And then it makes that upstreamable. You keep the default as
disabled, so nothing changes, but you allow people like you/Buildroot
who need those features to actually enable them. There's nothing "not
upstreamable" in those changes IMO, and it would anyway not be nice to
integrate a brand new package in Buildroot that has so many
non-upstream patches.

Please add explicit disable in "else" clauses:
ifeq (...)
FOO_CONF_OPTS += --enable-bar
else
FOO_CONF_OPTS += --disable-bar
endif

Meh, can we instead rely on existing architecture options, like MMX,
SSE, AVX, NEON, etc. to decide whether to enable SIMD or not?

Aside from those comments, looks good. Could you rework a bit, and
submit a v2?
Thanks a lot!

To: buildroot; +Cc: Michael Cullen, Thomas Petazzoni
This commit adds an image transformation library called zimg.
There are a number of patches applied. One is from upstream and supports
building on GCC-15, the others are autotools patches to allow installing
various components useful for verifying the library is working on the
target, which are not usually installed by the upstream project.
Note that while this version of zimg claims to support C++11 upwards,
upstream is moving towards only supporting C++17 upwards in the master
branch.
This has been tested on a Raspberry Pi 4 and a Raspberry Pi 5, and on
x86_64 (run in a chroot).

Changes V1 -> V2:
- Submitted PR upstream with patches
- Changed help text to reference "gcc >= 4.9" rather than just "C++11"
- Added explicit "--disable-..." configure options
- Removed "disable SIMD" option as requested. This option was only there
because the upstream configure script supports it so I decided to expose
it. It probably isn't very useful in normal situations though
