Re: [ft-devel] I would draft some documents to build SVG Native Viewer...

[suzuki toshiya]

Dear Moazin,

The current status of my document is like this:
https://github.com/mpsuzuki/svg-native-viewer/blob/cairo-cpp11/README.md

Dirk told me that current Skia backend is designed for m70.

Also, maybe by some accident, Skia backend is forcibly disabled
if the platform detected by cmake is not Apple. I tweaked these
issues by this changeset.

https://github.com/mpsuzuki/svg-native-viewer/commit/76cda7dc39a4326f829580b860a854ad23b80b75

However, it is not sufficiently flexible. I hardwired the location
of libskia.

Regards,
mpsuzuki
