Comment:
As a rule of thumb you usually do not depend on anything `chroot-...` because it is, well, in the chroot anyway.
That's why I thought that perhaps you meant
```
if [ "$CHROOT_READY" -a "$CROSS_BUILD" ]; then
        hostmakedepends+=" cmake"
fi
```
We need to test that anyway... I'll close my PR, your's is better.
