This was broken by commitdf08c37a42(cmGlobalGenerator: Add unity/pch sources after computing compile features, 2024-02-02, v3.28.3~1^2~1^2), and 3.28.2's commit76b5383123(cmGlobalGenerator: add unity sources after computing target compile features, 2024-01-01, v3.28.2~17^2~1). The problem is very similar to that fixed by commit4e8f24e977(PCH: Clear link interface cache when adding PCH object to it, 2022-01-24, v3.23.0-rc1~44^2~9). Generalize that fix. Fixes: #25696
