Why does marking an enum as exported/imported break Doxygen generation?

Question

Using Doxygen, I stumbled across this warning:

D:/<some/path>/Camera.h:20: warning: documented symbol `enum DLLPORT 
ct::CameraCapture::ct::CameraCapture::CamType' was not declared or defined.

Now I know why Doxygen does not find that class (the namespaces are obviously duplicated), what I don't understand is why it is even searching for it. This enum is in a header file, directly above a class definition, and the class is found fine, it also doesn't get those double namespaces generated. The source code compiles, too, so it probably isn't a syntactic error that is causing Doxygen these problems. Specifically, the source code looks like this:

#ifdef CT_EXPORTS
#define DLLPORT __declspec(dllexport)
#else
#define DLLPORT __declspec(dllimport)
#endif

#include <somelibrary>

namespace ct {
namespace CameraCapture {

/**The type of camera used:
*[...]
**/
enum DLLPORT CamType {
    CT_ENUM1=0,
    CT_ENUM2,
    CT_ENUM3,
    CT_NONE
};

/**\brief A parent-class to cameras of all types.
*[...]
**/
class DLLPORT Camera
{
   //...some content...
};
}
}

This same problem occurs with other enum blocks, too. Hopefully some of you guys know what is happening there.

Cheers

You don't need to dllexport nor dllimport enums. They're mere declarations of a type, not of code. Just use enum CamType. Classes (either en'masse or by-member) will need it, as will individual free functions, but simple enums do NOT.
