[CMake] How to check if Eclipse CDT4 generated project is set up correctly?

[Nils Rathmann]

Hi,
when I setup with the Eclipse CDT4 generator, as described here: 
https://cmake.org/Wiki/Eclipse_CDT4_Generator4

my [Targets] folder contains virtual folders for CMakeRules, Header 
Files, Object Files, Resources and Source Files, but only the source 
files folder is filled. The other folders are always empty, even if I 
build the target or the whole project. Is there a documentation where I 
can see how a generated Eclipse project should look like? When I compare 
my project with the sample screenshot in the wiki linked above, it looks 
totally different (mine has a lot of virtual folders like Subprojects, 
Targets, ...)

To summarize: Is there a description how a Eclipse CDT4 generated 
project should look like and how to use it best?

Details:
- OpenSUSE 13.2; Eclipse Mars  (4.5) with CDT 8.8.1.201602051005; cmake 
3.5.0
- Project created with cmake-gui as out-of-source build next to the 
source directory.

Thank you,
Nils
