thorvg: add recipe

Specify library name and version: thorvg/*

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

@RubenRBS
Would you please assist me as I don't have many recipes that I can refer to regarding meson?
I seem to get an error with the following code when I specify a BACKEND to MensonToolchain.

meson = Meson(self)
meson.install()

The error is as follows.

... \src\meson.build:1:0: ERROR: Tried modify read only option 'backend'

Is there a problem with the way my conanfile.py is written and is there a workaround?

[AbrilRBS]

Hi @toge, I've pinged @franramirez688 which is more faimiliar than I am with Meson to take a look into this, thanks for the contribution as always, let's see what they find about your error :)

@RubenRBS
Thanks a lot!

@toge FYI, I was having a look at this with @franramirez688 and we found a bug for the backend='vs' in Meson during the install step in package() method. We will report it upstream to get it fixed in new releases.

Meanwhile, we realized that using backend='vs2022' worked without issue, so let's try that in the recipe for now 😄 Thank you!

@danimtb
Thanks a lot!
I will try to fix it.

Hi @toge

I've been working on this conan-io/conan#15706
That PR is removing the reconfigure process, so we shouldn't have any problem keeping the original vs backend. I think we can wait for it and try this PR again using Conan's latest version.

@franramirez688
Thank you for information!
I'm waiting for it.

[franramirez688]

Minor suggestions, otherwise, it looks great.

@franramirez688
Thank you for your review and updating this PR!
I am waiting for updating conan 1.64.0 in CCI.
