# Makefile for Linux and Mac OSX systems for REGENIE
#
# * User needs to specify BGEN_PATH which is the directory
# 	where the BGEN library is installed
# * If the Boost Iostream library is installed on the system,
# 	user can specify to link to it during compilation by
# 	setting  HAS_BOOST_IOSTREAM to 1

# Optional: To use external BLAS/LAPACK routines in Eigen	
#
# For Intel MKL, add path of installed library to MKLROOT
# For OpenBLAS, add path of installed library to OPENBLAS_ROOT
#   note: it also requires lapacke library
#  
# For static compilation on Linux systems, set STATIC=1
#   -> this excludes GLIBC
