When I build the most recent revision in SVN, 4965, with Eigen2
installed, it fails to compile due to an ambiguous overloaded call to
Matrix. But with Eigen3 installed, it works.
The below patch seems to fix by building distgeom.cpp when only Eigen3
specifically is present.
I don't really understand the relationship between distgeom.c and
"obdistgen" or how cmake works, so I don't know if this the correct
way to do it.
I first tried changing just the tools/CMakeLists.txt to include
obdistgen only upon EIGEN3_FOUND, rather than HAVE_EIGEN, but that did
not solve the issue.
Cheers,
Jeff
