Install docs / Conda env

[pebert]

Building/installing Shogun can be a bit involved, the following process may be used as a working example. Using the Conda package manager, one creates a dedicated environment:

name: shogun
channels:
  - bioconda
  - conda-forge
dependencies:
  - cmake
  - ccache
  - atlas
  - hdf5
  - lapack
  - clapack
  - openblas
  - swig=3.*
  - eigen=3.*
  - nlopt
  - curl
  - openssl
  - python=2.7
  - numpy
  - java-jdk

Create the above environment, activate it, clone the dev branch of Shogun (this process worked with shogun_5.0.0-602-g86ca84e) and follow Shogun's installation instructions; specifically, call cmake as follows

cmake
-DPythonModular=ON
-DBUILD_META_EXAMPLES=OFF
-DCMAKE_PREFIX_PATH=/MY-PATH/TO/conda/envs/shogun
-DCMAKE_INSTALL_PREFIX=/MY-PATH/TO/conda/envs/shogun
-DSWIG_EXECUTABLE=/MY-PATH/TO/conda/envs/shogun/bin/swig
-DBUILD_EXAMPLES=OFF

Assuming that this worked, call afterwards:

make && make install

If everything works, this will install Shogun in the Conda environment, i.e., Shogun will be available as soon as the environment is activated.

As an update, I just confirmed that the above still works with the last major release of Shogun 6.0.0

Thanks, that is very helpful. I will update the README accordingly.
