Obviously, the help in developing and testing is appreciated, but for
the particular problem in question the patch is required for the
Eclipse plugin. There are a few things that need to be worked on in
the generator that can be of great help, but I'm not sure that
.project/.cproject in the source directory is the right solution. More
below...

Exactly, the bug is in the Eclipse plugin... CMake is just too
powerful for it ;)

I'm certainly not, but I'm only the author of the CDT4 generator not a
CMake developer ;)

I really don't think it would be appropriate to do this, however it
might be a reasonable compromise to have an option to generate the
files in the source dir even for an out-of-source build. But the
default should be the CMake way, since this is what is expected by
users.

Again I'm not in the CMake Dev Team, so I can't answer this. However,
I firmly believe that the .project/.cproject need to be created in the
binary directory (e.g., myapp-build). That is not to say that you
should stop doing something that works fine for your case, but in
general I encourage out-of-source builds and definitely CMake should
not generate files outside the binary directory (note that if it's an
in-source-build the binary and source are the same, but that is the
user's choice and not a CMake imposition).

What I would really like to do is to make eclipse projects support a
set of cvs/svn sources that are outside the dir where the .project is.
Unfortunately, I don't have the time right now to work on this and
don't know how open are the eclipse cdt developers to these changes.

That being said, I'm interested in solving any problems that arise
with the CDT4 generator and am willing to go through the patches and
test them. I also attend to all bugs submitted through the bug
tracker. And I certainly appreciate any effort in making the generator
better.

Just my 2 cents,
