Building on MSYS2 UCRT64 fails due to missing gvncpulse-1.0 and libssh_threads

[agerwick]

I've installed the following dependencies:
$ pacman -s mingw-w64-ucrt-x86_64-meson mingw-w64-ucrt-x86_64-python mingw-w64-ucrt-x86_64-meson mingw-w64-ucrt-x86_64-ninja mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-gtk3 mingw-w64-ucrt-x86_64-libssh mingw-w64-ucrt-x86_64-gtk-vnc mingw-w64-ucrt-x86_64-gtkmm3 mingw-w64-ucrt-x86_64-cmake

and I end up with these specific versions:
mingw-w64-ucrt-x86_64-meson-1.6.0-2
mingw-w64-ucrt-x86_64-python-3.12.7-2
mingw-w64-ucrt-x86_64-ninja-1.12.1-1
mingw-w64-ucrt-x86_64-gcc-14.2.0-2
mingw-w64-ucrt-x86_64-gtk3-3.24.43-1
mingw-w64-ucrt-x86_64-libssh-0.11.1-1
mingw-w64-ucrt-x86_64-gtk-vnc-1.3.1-2
mingw-w64-ucrt-x86_64-gtkmm3-3.24.9-1
mingw-w64-ucrt-x86_64-cmake-3.31.0-1

But there are two dependencies that I can't find, gvncpulse-1.0 and libssh_threads.
Where can I find these?
Alternatively, is there a pre-built Windows executable available? I have not tried building on Windows before...

Here's the complete output:

gvncpulse and libssh_threads are both optional, and are not currently used in Windows builds.

Also, Windows installers can be found on the releases page (e.g. https://github.com/zrax/gsshvnc/releases/tag/v0.96)
