# Optional cross-compilation targets.
#
# By default this CMakeLists only builds the native libghostty-vt so
# that local `make build` / `make test` cycles stay fast. CI opts in
# to specific cross targets by passing this variable, which produces
# the corresponding `ghostty-vt-static-<NAME>` IMPORTED target with
# outputs under `build/ghostty-<NAME>/`.
#
# The value is a semicolon-separated list of `<name>=<zig-target>`
# entries, e.g.:
#
#   cmake -B build \
#     -DGHOSTTY_VT_CROSS_TARGETS="linux-amd64=x86_64-linux-gnu"
#
# Multiple targets can be configured at once by separating with `;`.
