[CMake] Re: Out of source build and KDevelop

[Bill Hoffman]

GetHomeDirectory will return the very top level directory.
However, you should not need it for each project.  The
map < name, vector<local gen> > will have the name
of each project and a vector of local generators.  The first
local gen in each vector will be the one for the cmakelist
file that contained the PROJECT(name) command that matches the
name in the map.   So, to get the toplevel source directory for
a project, you can get the binary and source dir from the cmMakefile
of the local generator.   I am assuming that each sub project does
not need to know the top of the entire project, just the top for
itself.
