Add a top-level CMakeLists.txt that wraps `zig build lib-vt` so that
CMake-based downstream projects can consume libghostty-vt without
needing to interact with the Zig build system directly. A custom
command triggers the zig build during `cmake --build`, and the
resulting shared library is exposed as an IMPORTED target.
Downstream projects can pull in the library via FetchContent, which
fetches the source and builds it as part of their own CMake build, or
via find_package after a manual install step. The package config
template in dist/cmake/ sets up the ghostty-vt::ghostty-vt target
with proper include paths and macOS rpath handling.
A c-vt-cmake example demonstrates the FetchContent workflow, creating
a terminal, writing VT sequences, and formatting the output as plain
text. CI is updated to auto-discover and build CMake-based examples
alongside the existing Zig-based ones.
This is an update to address common agentic issues I run into,
but the `build.nu` script may be generally helpful to people using
the Nix env since `xcodebuild` is broken by default in Nix due to the
compiler/linker overrides Nix shell does.
This should make testing Flatpak builds a lot easier.
To build, enter `flatpak/` directory and run:
flatpak-builder --repo=repo builddir com.mitchellh.ghostty.yml
alternatively, using org.flatpak.Builder flatpak:
flatpak run -p org.flatpak.Builder \
--repo=repo \
builddir \
com.mitchellh.ghostty.yml
The resulting flatpak can be installed using
flatpak install ./repo com.mitchellh.ghostty

This fixes a regression in 1.1.1/1.1.2 where our PACKAGING docs mention
using `fetch-zig-cache.sh` but it was removed. This commit adds it back,
generating its contents from the build.zig.zon file (via zon2nix which
we use for our Nix packaging).
For packagers, there are no dependency changes: you still need Zig and
POSIX sh. For release time, Ghostty has a new dependency on `jq` but
otherwise the release process is the same. The check-zig-cache.sh script
is updated to generate the new build.zig.zon.txt file.
This brings the internal package more in line with how the nixpkgs
package is built. It also handles recursive dependencies better than the
current system.
