That's correct.  The GNU make manual says, in the second paragraph of
the section "Target-Specific Variable Values":

        As with automatic variables, these values are only available
        within the context of a target's command script (and in other
        target-specific assignments).

Since we don't really know what you're trying to do we can't give you a
range of suggestions on how to do it.

However, the only way to do exactly what you're trying to do is to use
$(eval ...).  There are other, simpler ways to do things if what you're
trying to do doesn't require the full flexibility of eval.
