cmDepends: allow multiple dependees per depender
This patch is heavily inspired by Michael Wild. The interfaces cmDepends::Write and cmDepends::WriteDependencies where extended to allow multiple dependees (sources) per depender (object). cmDepends::Write first collect all dependencies into a std::set before passing it to cmDepends::WriteDependencies. cmDependsC::WriteDependencies also first collects all explicit and implicit dependencies into a std::set and only then writes depend.{internal,make}. The implementation of cmDependsFortran simply loops over all sources and proceeds as before, whereas the cmDependsJava implementation is as trivial as before. This is for preventing exponential growth of depend.{internal,make} in the next commit which fixes dependency-vector erasure in cmDepends::CheckDependencies. Inspired-by: Michael Wild <themiwi@users.sourceforge.net>
