The new v0.25.0 release of cbindgen adds a
--depfileoption, that CMake can use to determine when to re-run cbindgen.This feature requires the
DEPFILEparameter ofadd_custom_commandand is available on most generators by now.If CMake is too old, or the Generator does not support
DEPFILE, then we fallback to always rerunning cbindgen as before.
