When processing an indirect dependency of target `A` on target `C` via an interface library B, `cmComputeTargetDepends::AddTargetDepend` was not checking for duplicate dependencies, so that if `A` depended on `C` via multiple interface libraries, the dependency graph built in cmComputeTargetDepends would have duplicate edges. In a real project (LLVM libc) this was causing cmake to consume multiple gigabytes of RAM. Fixes: #27386
