@ -1079,6 +1079,11 @@ additional paths to be searched when linking target binaries to be introspected.
`qemu-<target_arch>-static` when running the target binary. You can for example specify
`GIR_EXTRA_OPTIONS="-strace"` to see a trace of what happens when running that binary.
- `meson` creates a cross file, `${XBPS_WRAPPERDIR}/meson/xbps_meson.cross`, which configures
meson for cross builds. This is particularly useful for building packages that wrap meson
invocations (e.g., `python3-pep517` packages that use a meson backend) and is added by default
for packages that use the `meson` build style.
- `qemu` sets additional variables for the `cmake` and `meson` build styles to allow
executing cross-compiled binaries inside qemu.
It sets `CMAKE_CROSSCOMPILING_EMULATOR` for cmake and `exe_wrapper` for meson
