The problem is in cmLocalGenerator::ComputeLinkInformation()

    // For backwards compatibility variables may have been expanded
    // inside library names.  Clean up the resulting name.
    std::string lib = j->first;
    std::string::size_type pos = lib.find_first_not_of(" \t\r\n");
    if(pos != lib.npos)
      {
      lib = lib.substr(pos, lib.npos);
      }
    pos = lib.find_last_not_of(" \t\r\n");
    if(pos != lib.npos)
      {
      lib = lib.substr(0, pos);
	//** this code always eats the fist char **
      }
    if(lib.empty())
      {
      continue;
      }
