There are two problems to use cache-native now:
* ccache-native depends on cmake-native and zstd-native which makes it
requires
more time to build, so it might be a bottleneck for the build
* We need disable ccache-native for about 20 native recipes to resolve the
circular dependency.
It seems that there isn't a good way to fix the problem, or we have to
disable
ccache for native recipes, only make other recipes (cross, target and
nativesdk)
use ccache-native.
Host's ccache isn't reliable from the history.
We had the same problem with icecream and solved it by building in a docker
container with the version of ice cream that we wanted FWIW.
Alternatively, I think it's possible to roll your own buildtools that has
ccache?
Yes, thanks, it's a good suggestion.
