missing eigen3 includes

[josch]

Hi,

since ply_c requires eigen3, this requirement should be stated in the CMakeLists.txt without it, the compilation will not be able to add the eigen3 include directories. Here is a patch that worked for me:

diff --git a/partition/ply_c/CMakeLists.txt b/partition/ply_c/CMakeLists.txt
index 169c98f..eaedb5a 100644

Thanks, that's useful. Adding it to the pile for the 0.2 version.
