[Bf-committers] CMake+MSVC workarounds for recent /WX and MT changes

Hello there,
there are two set of problems stopping blender for building on MSVC +CMake.
I have they working (locally) with some tweaks, but it would be nice to find
what is the right way to do it.

1) The first one is regarding warnings (WX):
Blender will crash for some of the warnings in smoke, custom_data and ffmpeg
projects. The kind of error we get is:
 - trunk\source\blender\blenkernel\intern\smoke.c(148) : error C2220:
warning treated as error - no 'object' file generated

The fix I'm applying locally is:
http://www.pasteall.org/16439/diff (basically casting ints to unsigned int -
as commented in previous email)

2) Multithreading is crashing things here. I noticed recent commits for
scons (and attempt ones for CMake) regarding this, but for me it's still
Following the instructions from here
http://msdn.microsoft.com/en-us/library/Aa267384 I managed to build again
going to the "blender" project and changing the ignored libraries from
libc.lib to:

I guess I could change it in CMakeLists.txt - e.g.::
+SET(PLATFORM_LINKFLAGS "/NODEFAULTLIB:libc.lib msvcrt.lib libcd.lib
libcmtd.lib msvcrtd.lib")

Does anyone know if this is the way to go?
