Summary:                    Issues with the 'Eclipse CDT4 - NMake Makefiles'
Generator
Description: 
The project compiles and links in Eclipse but the preprocessor symbols are not
defined by the .cproject file.  As a result, sections with

#ifdef _WIN32
#endif

appear grayed out in the IDE and any included files can't be opened.  Note that
I'm using Eclipse 4 (Luna).

Is there any way I can ensure that the Eclipse project has knowledge of my
toolchain's preprocessor symbols without having to redefine them all in my
CMakeLists.txt file(s)?

Steps to Reproduce: 
1) setup project with in source build for better eclipse support (see
http://www.cmake.org/Wiki/Eclipse_CDT4_Generator)

2) run cmake with the following (please see attached toolchain file for
reference):

olchain_windows_vsc.cmake -G "Eclipse CDT4 - NMake Makefiles"

3) import the project into Eclipse, right click on the project, go to Properties
-> C/C++ General -> Paths and Symbols and notice that there are no symbols
defined.  There is not even a Symbols tab which is typically the case for a
valid CDT project.
