As I said, the issue with the version control.
Then it doesn't recognize if a linked resource points to a file which is 
already part of the project, and considers those two separate files.
There is a setting somewhere to exclude linked resources from the search, but 
that setting is stored neither in the .project nor in the .cproject file.
It can't handle linked resources which point to a parent directory of the 
directory where the .project file lives.
Many of these problems would be solved if the .project file could have an 
entry which specifies the root source/project directory for Eclipse.

cmake adds the builtin include dirs and the project-include dirs to the 
include dirs of Eclipse, so Eclipse should be able to find the headers.

Can you create a small project which shows the problem and send me the 
.cproject file, or put them into a ticket on http://public.kitware.com/Bug ?
