[CMake] Eclipse .cproject Preprocessor Macro Definitions

[Ette, Anthony (CDS)]

To Whom It May Concern:

I'm using Cmake 3.2.2, specifically the "Eclipse CDT4 - NMake Makefiles" generator.  I am able to successfully run cmake and build from within Eclipse but there seem to be things missing from the .cproject file.  For example, I've got a source routine with #ifdef _WIN32 and this chunk of code is greyed out (i.e. not perceived active) in the Eclipse editor and source outline views (see picture below).  I find this surprising since the build succeeds (it's ultimately able to find the necessary windows headers) and /DWIN32 is defined in CMAKE_CXX_FLAGS.

Can you explain why the Eclipse project is unaware of the toolchain preprocessor macros and elaborate on how I can control this behavior using cmake (i.e. what knobs do I have at my disposal to tweak the .cproject file that gets generated by the Cmake generator, if any)?

Thank you for your time and support,
