Eigen dependency

[ChristianMichelsen]

Hi,

Is Eigen a new, required, dependency? After pulling the latest changes and running make I get:

HTSSRC not defined, assuming systemwide installation -lhts
echo '#define METADAMAGE_VERSION "18f7f72"' > version.h
c++ -c  -O3 -std=c++11   main_pmd.cpp
c++ -MM -O3 -std=c++11   main_pmd.cpp >main_pmd.d
c++ -c  -O3 -std=c++11   metadamage.cpp
In file included from metadamage.cpp:18:
./regression.h:3:10: fatal error: 'eigen3/Eigen/Core' file not found
#include <eigen3/Eigen/Core>
         ^~~~~~~~~~~~~~~~~~~
1 error generated.
make: *** [metadamage.o] Error 1

Yes I think it is used as minimizer, do you prefer gsl?

Nah, it was just a new, undocumented dependency.
Is it possible to make it an optional dependency since we do not use it in metaDMG?

If not, the good thing is that it's easy to install with Conda and/or Homebrew.

I have removed the dependency of eigen3

As far as I see, it is still a problem.
