Cannot use different module aliases of dependency in the same package

[ahoppen]

If you have a package with two targets like

.target(
name: "LibA",
dependencies: [.product(name: "Crypto", package: "swift-crypto")]
),

.target(
name: "LibB",
dependencies: [.product(name: "Crypto", package: "swift-crypto", moduleAliases: ["Crypto": "CryptoAlias"])]
),

then compilation will fail with error: no such module 'CryptoAlias'. We should be building swift-crypto twice, once with the module alias and once without so that both LibA and LibB can build.
