There is an Eclipse CDT 4.0 generator being developed on top of the Makefile generators available now (i.e., "Unix Makefiles", "MinGW Makefiles", "MSYS Makefiles", and maybe "NMake Makefiles").
With this generator it is possible to create a set of .project/.cproject files that can be imported in Eclipse as an "Existing Eclipse project".
Since August 1st the Eclipse generator is included in CMake cvs.
If you would like to monitor the changes to the EclipseCDT4 support, you can view the following links which contain the cvs history log for changes to the two main files:
* [http://www.cmake.org/cgi-bin/viewcvs.cgi/Source/cmExtraEclipseCDT4Generator.h?root=CMake&view=log cmExtraEclipseCDT4Generator.h]
* [http://www.cmake.org/cgi-bin/viewcvs.cgi/Source/cmExtraEclipseCDT4Generator.cxx?root=CMake&view=log cmExtraEclipseCDT4Generator.cxx]
==Using Eclipse CDT4 Generator==
Using the Eclipse CDT4 generator is not different as using another CMake generator.
In this example I assume the source tree of my project
is ''/home/eric/certi_src''
<li> Create a build directory and goes there
    <pre>mkdir /home/eric/certi_build
          cd /home/eric/certi_build</pre>
<li> Launch CMake
    <pre>cmake -G"Eclipse CDT4 - Unix Makefiles" ../certi_src</pre>
After that you will find two eclipse file in your build tree:
    <li> <tt>certi_build/.project</tt></li>
    <li> <tt>certi_build/.cproject</tt></li>
<li> Import the created project file into Eclipse:
    <li> Launch eclipse</li>
    <li> Import project using Menu ''File->Import''
          [[Image:Capture-EclipseMenuFileImport.jpg|thumb|center|200px|Eclipse Menu->File->Import]]</li>
    <li> Select ''Existing projects into workspace'':
          [[Image:Capture-EclipseProjectsIntoWorkspace.jpg|thumb|center|200px|Existing Projects into Workspace]]</li>
    <li> Browse where your build tree is and select the root build tree directory
          [[Image:Capture-Import.jpg|thumb|center|200px|Eclipse Import after build tree selection]]</li>
    <li> You get a fully functionnal eclipse project
          [[Image:Capture-certi_build-Eclipse.jpg|thumb|center|200px|Eclipse Imported CERTI project]]</li>
==Using Eclipse CDT4 Generator (CVS enabled project)==
There is a limitation of the CMake CDT4 Eclipse generator when
your source tree is handled by a versioning system (like CVS, Subversion or other)
you may read the referred discussion in the link below.
A may acceptable ''solution'' is to have 2 projects:
<li> one for version management
    This one may be obtained by a normal ''checkout'' using </li>
<li> one the building resulting from the imported CMake generated project</li>
You will find a screen cast describing how to it
here: [[CMakeEclipseCDT4andCVS-2.ogg]]
==Discussion about Eclipse CDT4 Generator limitations==
Eclipse assume project files (i.e. .project and .cproject) ''must
be at the root of the project tree'' '''and''' a project
may be handled by a versioning system (CVS, SVN, ...) iff
''the root project tree is''.
This assumption clashes with the fact that CMake generated files
should ''stay in the build tree'' whereas source files (which are usually those handled
by a versioning system) reside ''in the source tree''.
There has been a fair amount of discussion regarding this '''problem'''
of the Eclipse CDT4 Generator:
<li>[http://www.cmake.org/pipermail/cmake/2007-October/016956.html Trouble with CMake + Eclipse + SVN/CVS]
<li>[http://www.cmake.org/pipermail/cmake/2007-August/015504.html *Updated* Eclipse CDT4 CMake Generator - Pre-Alpha version]
