I did not follow the full-thread, just reading this Email and I hope I'm 
getting it right:

We had the same problem (relative paths) and it turned out to be 
relatively (got the language joke here? ;)) easy, at least with cmake 2.6, 
in a local project.

set(CMAKE_USE_RELATIVE_PATHS ON)

It works well for vcproj-generation. In Linux I could not test it 
comprehensively yet (as to why it is possible to copy a repository and 
build it in its new place w/o re-cmaking.)

In addition we are setting

set(CMAKE_SUPPRESS_REGENERATION ON)

in order to not have a dependency on the CMakeLists when creating the 
vcproj-file.

HTH,
Patrick.
