Since commit v2.8.0~27 (Major optimization of C/C++ dependency scanning, 2009-09-23) our `VaildDeps` cache of `depend.internal` content is supposed to avoid re-scanning dependencies of object files whose dependencies have not changed. However, this was broken by changes to `cmDependsC::WriteDependencies` by commit v3.1.0-rc1~272^2~1 (cmDepends: Refactor object file path conversion, 2014-07-22). The object file path written to `depend.internal` was changed to a relative path, but the lookup in the `ValidDeps` cache of that information was not updated too. Therefore the cache is not used. Fix the object file path used for the `ValidDeps` lookup to restore the original optimization.
