Typically, you'd want your export sets to not be overlapping and to contain
no cyclic dependencies. If you have a target in multiple export sets, it
suggests that you probably should factor out that target to a separate
export set that other exports then depend on. That said, if you have a
scenario that legitimately requires a target in multiple export sets, then
you would need to use multiple install() commands to achieve this,
specifying a different export set for each one.
