- Thread-topic: [cdt-dev] Exact purpose of CDT_SOURCE and CDT_OUTPUT pathentries ?
I don't really have an answer. But as I've mentioned to CMake developers in the past, the .cproject file is an internal file that can change format or even disappear at any time. In fact, we're moving more of our settings to project scoped preferences as we go.
For me, I get the most value out of CMake when it generates Makefiles and I can call them from CDT's Makefile projects. I have on my wish list a way to automate setting up projects like that at some point with a New Project wizard.
The point is CDT isn't like XCode or VisualStudio. It's actually, probably, at the same level as CMake, since it's really platform agnostic.
