If feasible please add protoc and WellKnownTypes.proto to windows zip

[gmabey]

Thank you very much for the windows precompiled .zip file!

As a follow-up to one of the comments in #188, this asset would be even more useful if it included protoc and the .proto files that correspond to the WellKnownTypes.

Oh, that's quite hard, but I will try, also I don't really want to distribute 'protoc'. But I look into :)

[gmabey]

Thank you for considering it. I'm not sure what the right thing to do is (either way) but I'm sure that it would be really nice (like, minimizing how much one has to mess around with windows) if the only action required to be able to use QtProtobuf were to unzip a single file and append -DCMAKE_PREFIX_PATH=c:\path_to_unzip\lib\cmake. The specific error I'm getting is this:

which doesn't look like it's even using the .zip file yet -- instead some remnants of my build-qtprotobuf-from-scratch effort are cropping up. If I was better at cmake+windows issues, I would have a better chance of making sense of this.

Anyway, that's my 2 cents ...

[gmabey]

I was able to resolve some of my issues, but thought that I would contribute some of experiences.

I tried again to use the precompiled .zip of .lib files, and now I'm getting this error:

Qt5Protobuf.lib(qtprotobuf.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in mocs_compilation.cpp.obj
Qt5Protobuf.lib(qtprotobuf.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in mocs_compilation.cpp.obj

I assume this means that I need to compile QtProtobuf myself, right?

Also, I retract my request to include protoc and .proto files in the .zip ... closing.

[semlanik]

Sorry, I'm not so good in Win32 ABI so I need time to make all this mess work correctly. Perhaps I miss some compiler/linker flags.

[gmabey]

Yeah I'm no good with the Win32 stuff either ...

I think it's just worth helping users realize somehow that the .zip file might not work as smoothly as we all wished -- at least not for now.
