Makefile

# Makefile for a Linux/GCC build of CNTK
#
# The Linux and Windows versions are not different branches, but rather build off the same
# source files, using different makefiles. This current makefile has the purpose of enabling
# work to make all sources compile with GCC, and also to check for GCC-compat regressions due to
# modifications which are currently done under Windows.
#
# To use this Makefile, create a directory to build in and make a Config.make in the directory
# that provides
#   BUILDTYPE= One of release or debug
#     defaults to release
#   ACML_PATH= path to ACML library installation
#     only needed if MATHLIB=acml
#   MKL_PATH= path to CNTK custom MKL installation
#     only needed if MATHLIB=mkl
#   CNTK_CUSTOM_MKL_VERSION=2
#     version for the CNTK custom MKL installation
#   MKL_THREADING=parallel|sequential
#     only needed if MATHLIB=mkl
#   GDK_PATH= path to cuda gdk installation, so $(GDK_PATH)/include/nvidia/gdk/nvml.h exists
#     defaults to /usr
#   MATHLIB= One of acml or mkl
#     defaults to acml
#   CUDA_PATH= Path to CUDA
#     If not specified, GPU will not be enabled
#   CUB_PATH= path to NVIDIA CUB installation, so $(CUB_PATH)/cub/cub.cuh exists
#     defaults to /usr/local/cub-1.4.1
#   CUDNN_PATH= path to NVIDIA cuDNN installation so $(CUDNN_PATH)/cuda/include/cudnn.h exists
#     If not specified, CNTK will be be built without cuDNN.
#   KALDI_PATH= Path to Kaldi
#     If not specified, Kaldi plugins will not be built
#   OPENCV_PATH= path to OpenCV 3.0.0 installation, so $(OPENCV_PATH) exists
#     defaults to /usr/local/opencv-3.0.0
#   LIBZIP_PATH= path to libzip installation, so $(LIBZIP_PATH) exists
#     defaults to /usr/local/
# These can be overridden on the command line, e.g. make BUILDTYPE=debug

# TODO: Build static libraries for common dependencies that are shared by multiple 
# targets, e.g. eval and CNTK.
