• remove from baseline.
• switch to meson.
  depends on [qt] Fix qtmultimedia with gstreamer on windows #20555 to solve the qtmultimedia regression

[Neumann-A]

Hmm CI logs tell me:
a) Linux pc file for openssl seems to be broken
b) Some linkage issue on osx which requires an extra log CI is not giving me.

[Neumann-A]

@dg0yt:
You are currently fixing some pc files and dependencies. Have you seen the usage of openssl via *.pc files in there somewhere?

[dg0yt]

@Neumann-A I can't say for sure. Every project hacks it is own way around issues on some build environment, instead of just using pkg-config. I can check linux later, but my native mingw buildtree is discouraging:

 $ grep PKG_CHECK buildtrees/*/src/*/configure.ac  | grep "ssl\|crypto"

(No results)

[dg0yt]

On linux, I had one hit: nghttp2.
However, it looks for module "openssl". This module exists in my Ubuntu system, but vcpkg port openssl only creates libssl.pc and libcrypto.pc.

(The Ubuntu module basically just Requires: libssl libcrypt.)

[dg0yt]

On linux, I had one hit: nghttp2.

(And nghttp2 has no openssl dependency in vcpkg.)

@NancyLi1013: Since you put libnice on the ci skiplist, I'll let you figure out what is going on with gstreamer on osx. The linux build failure here is due to a missing openssl.pc from the openssl port within vcpkg.

I skipped on the ci is just to solve the problem that the website cannot be accessed, please see #16473 (comment). It is just a temporary fix.

The failures caused by gstreamer on osx are like this:

../src/1.19.2-dbedf5df9d.clean/meson.build:322:6: ERROR: Problem encountered: Failed to link with version script (/Users/vagrant/Data/buildtrees/gstreamer/src/1.19.2-dbedf5df9d.clean/gstreamer-full-default.map), check logs for details

A full log can be found at /Users/vagrant/Data/buildtrees/gstreamer/x64-osx-dbg/meson-logs/meson-log.txt

But I cannot get the details from /Users/vagrant/Data/buildtrees/gstreamer/x64-osx-dbg/meson-logs/meson-log.txt. I'm not sure what happened on this. I tried to reproduce this on my local machine, but was blocked by other problem.
@strega-nil, could you please help provide the details from /Users/vagrant/Data/buildtrees/gstreamer/x64-osx-dbg/meson-logs/meson-log.txt or how can we get this file?

For the problem on Linux:

@Neumann-A ,Is this PR being worked on?

[Neumann-A]

@JonLiu1993 Not by me. I can close it if you want. (see #20556 (comment))

[github-actions]

You have modified or added at least one vcpkg.json where a "license" field is missing.

If you feel able to do so, please consider adding a "license" field to the following files:

• ports/libnice/vcpkg.json

Valid values for the license field can be found in the documentation

Thanks for the update!

The openssl pkgconfig dependency should have been fixed by #20831
