[CMake] GUIDs in VS solution files

[Vincent Scheib]

Indeed, the first GUID in the project definition line indicates the
project type (C++, C#, Visual Basic...). The
INCLUDE_EXTERNAL_MSPROJECT command needs to change the GUID based on
the project type.

Thanks for pointing this out.. ;) I just added some C# projects to our
solution, quite handy.

Here is a modification I've just made to add this functionality to CMAKE.

In CMAKE version 2.4.3

Modified Files:
.\Source\cmGlobalVisualStudio71Generator.cxx

- WriteExternalProject() member function modified to check the project type,
and use the appropriate project type GUID when writing the solution file.

Code snipit:
------------------------------
// Write a dsp file into the SLN file, Note, that dependencies from
// executables to the libraries it uses are also done here
void cmGlobalVisualStudio71Generator
::WriteExternalProject(std::ostream& fout,
                              const char* name,
                              const char* location,
                              const std::vector<std::string>& depends)
{
//*** BEGIN EMERGENT MODIFICATION
//*** support for external project files that are not C++

 // Create an uppercase version of location
 char* location_uppercase = NULL;
 {
     size_t location_strlen = strlen(location);
     location_uppercase = new char[location_strlen+1];
     strcpy(location_uppercase, location);
     for (char* c = location_uppercase; *c != NULL; c++)
     {
         *c = toupper(*c);
     }
 }

 // Check what type of project it is, to know what type of GUID to use.
 const char* project_type_guid = "8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942"; //C
 if (strstr(location_uppercase, ".CSPROJ"))
     project_type_guid = "FAE04EC0-301F-11D3-BF4B-00C04F79EFBC";
 if (strstr(location_uppercase, ".VBPROJ"))
     project_type_guid = "F184B08F-C81C-45F6-A57F-5ABD9991F28F";
 delete [] location_uppercase;
 location_uppercase = NULL;

 std::string d = cmSystemTools::ConvertToOutputPath(location);
 fout << "Project(\"{" << project_type_guid << "}\") = \""
      << name << "\", \""
      << d << "\", \"{"
      << this->GetGUID(name)
      << "}\"\n";

//*** END EMERGENT MODIFICATION
