Yes, that sounds good.  To get the correct names, I think you have
to move the code to the global generator and basically remove the kdevelop3
local generator.



Here are the changes I would like to see:


1. move cmGlobalVisualStudio7Generator::CollectSubprojects() and the map
 m_SubProjectMap  to the parent class cmGlobalGenerator so you can
use it in the kdevelop global generator.

// The function looks like this:
// populate the m_SubProjectMap 
void cmGlobalVisualStudio7Generator::CollectSubprojects()
{
  unsigned int i;
  for(i = 0; i < m_LocalGenerators.size(); ++i)
    {
    std::string name = m_LocalGenerators[i]->GetMakefile()->GetProjectName();
    m_SubProjectMap[name].push_back(m_LocalGenerators[i]);
    std::vector<std::string> const& pprojects 
      = m_LocalGenerators[i]->GetMakefile()->GetParentProjects();
    for(unsigned int k =0; k < pprojects.size(); ++k)
      {
      m_SubProjectMap[pprojects[k]].push_back(m_LocalGenerators[i]);
      }
    }
}


2. Add a Generate method to the kdevlop global generator:

void cmGlobalKdevelopGenerator::Generate()
{
  this->CollectSubprojects(); // call the parent class to fill m_SubProjectMap
   // Create a kdevlop3 project for each project in the project:

  for(it = m_SubProjectMap.begin(); it!= m_SubProjectMap.end(); ++it)
    {
    this->OutputKDevelop3Project(it->second[0], it->second);
    }

3.  Implement OutputKDevelop3Project something like this:

cmGlobalKdevelopGenerator::OutputKDevelop3Project(cmLocalGenerator* root,
                                std::vector<cmLocalGenerator*>& generators)
{
  // root is the top level project where you get the project name from
  std::string fname = root->GetMakefile()->GetStartOutputDirectory();
  fname += "/";
  fname += root->GetMakefile()->GetProjectName();
...

   // then collect up all the files in all the targets in the generators
   // vector.  This will contain the list of local generators for 
   // all sub projects of root

}
