[CMake] Eclipse generator question

[Benjamin Shadwick]

I tried cmake4eclipse, and it's a mixed bag. It requires a lot of tweaking
of the Eclipse project after you create it, and I'm pretty sure it suffers
from the same problem of leaving you with an Eclipse project whose source
tree reflects what is in the filesystem rather than what is defined in the
CMake project.

It's really annoying that I spent all this time building a CMake project
for a complex codebase, only to have the IDE present and index the entire
source tree on the filesystem instead of the subset that is actually being
built by the CMake configuration.

I should probably enhance my project-tweaking python script to add filters
to the generated Eclipse project to hide anything that isn't in the CMake
project.
