I can look into this but probably not within the next two weeks as I'm currently
trying to get this to "featurecompleteness" first and because I don't know that
process (msbuild) at all. OK, I don't expect to reach that within two weeks, but
I hope to have the most important items covered by then.
From a Visual Studio command prompt (probably the same one you use for nmake)  cause CMake to generate the appropriate output (not passing -G does that for me) then type `msbuild Wireshark.sln`.
It's make on steroids, but also works with Visual Studio solutions.  A Visual Studio solution (for 2010 onwards) is a set of xml files.  The .sln file lists all the projects aka targets, and each project file has all the instructions to build that project.

Sounds good to me. UseMakeDissectorReg.cmake only implements the python version,
no idea why I implemented the shell version in UseMakeTapReg.cmake.
I'll try these changes out on a Linux CMake build to make sure they don't break anything and then commit them.  Should I set UseMakeTapReg to use Python in all platforms or just Windows?

Again vs specific or with nmake as well?
All VS2010 solution.

That's again interesting. It works for me using cmd (on Win7). I'm not so sure
about the source of the problem. What do you get when you
dir E:/Wireshark/trunk/epan\\dissectos/packet-dua.c
Ah, forget it: Where does the spelling dissectos come from?
I know, it's really odd.  The command in the solution is built correctly.
