[CMake] Eclipse .cproject file (support for multiple build configurations)

[Ette, Anthony (CDS)]

To Whom It May Concern:

I'm using Cmake 3.2.2, specifically the "Eclipse CDT4 - NMake Makefiles" generator.  My application is multi-platform but common source.  We were using managed Makefiles for UNIX and Visual Studio solutions/projects for Windows but we'd like to ditch all of this in favor of the more flexible Cmake.  That said, we were using two different build configurations in our Eclipse projects and we would switch between active build configuration depending on which platform we were developing for at the time.  Using Cmake with the -G option I describe above seems to always result in a single build configuration (named "Configuration") in the Eclipse .cproject file.  Does Cmake Eclipse CDT 4 generator support multiple build configurations?  If so, how do I set it up?

On a related note: it seems as though cmake was designed assuming separate source for each platform but we have common source.  Ideally, we'd like all the targets to be defined within a single file (e.g. Makefile) so when we switch platforms, we don't have to rerun Cmake to regenerate Makefiles for that platform.  Can cmake handle this kind of setup or is the advise to just split the source and clone & own for each platform to avoid rerunning cmake when you switch?

Thank you for your time and support,
