Description

Created attachment 441
eigen-cmake-config.patch

The attached patch provides support for the cmake command

find_package (Eigen 3.2)

via eigen-config.cmake and eigen-config-version.cmake. This will be
able to find Eigen either in the build tree (after "cmake SOURCE_DIR")
or in the install tree (after "make install"). It sets Eigen_FOUND,
Eigen_VERSION, and Eigen_INCLUDE_DIRS. This is a "config-style" lookup.
If a user has a FindEigen.cmake in his path he might need to specify
NO_MODULE.
