Hello, I made these changes to build using system plutovg, in case you're interested!

Replacing line 20 of the PKGBUILD with...

git clone https://github.com/sammycage/plutovg.git

...fixes the following error

Please add rm duplicate plutovg files (probably best choice).

 cd ${pkgdir}/lunasvg/usr/ 
 rm ./include/plutovg/plutovg.h
 rm ./lib/libplutovg.a
 rm ./lib/pkgconfig/plutovg.pc
 rm -R ./lib/cmake/plutovg

or add plutovg as conflict, and add provide (probably

conflicts=('plutovg')
provides=('plutovg')

this version of svg2png in the package (currently already build). As several SVG libraries packages can have their own version to svg2png, it's better to add a suffix to know will algorithm/capabilities will be used.

 install -D655 /build/examples/svg2png /usr/bin/svg2png-lunasvg

I can't have both plutovg and lunasvg installed at the same time, as lunasvg tries to overwrite plutovg files:

error: failed to commit transaction (conflicting files)
plutovg: /usr/include/plutovg/plutovg.h exists in filesystem (owned by lunasvg)
plutovg: /usr/lib/cmake/plutovg/plutovgConfig.cmake exists in filesystem (owned by lunasvg)
plutovg: /usr/lib/cmake/plutovg/plutovgConfigVersion.cmake exists in filesystem (owned by lunasvg)
plutovg: /usr/lib/cmake/plutovg/plutovgTargets.cmake exists in filesystem (owned by lunasvg)
plutovg: /usr/lib/pkgconfig/plutovg.pc exists in filesystem (owned by lunasvg)

Adding to bartus comment the way you currently clone plutosvg expects a working ssh key setup this github. Instead clone over https should be used.

Small fix/improvement: include the plutosvg git sources in the sources[] array.

merge with: git am -s < <(curl -s http://0x0.st/K1F_.mbox)

Thank you for implementing them!

I added the proposed edits. Thanks.

Found another bug: because lunasvg builds static libs, it causes problems with lto builds. See https://archlinux.org/todo/lto-fat-objects/, tldr add CFLAGS+=" -ffat-lto-objects" to the PKGBUILD

Also, the new version defaults to installing to /usr/local (system packages should install straight to /usr).

To fix I added -DCMAKE_INSTALL_PREFIX=/usr/ in the configure stage
