* download and extract the official openQCD-1.2 package from

  http://luscher.web.cern.ch/luscher/openQCD/

  You will need to know the full path to openQCD-1.2/modules/
  

* edit the Makefie of the mesons package, which should be in ./build/Makefile
  The lines that need adjustment are the following:
  
  MDIR = ../../openQCD-1.2/modules
  # change this to your openQCD/modules path

  MPI_HOME = /usr/global/openmpi-1.6.5 
  # change this to your MPI implementation

  CFLAGS = -std=c89 -pedantic -fstrict-aliasing \
         -Wall -Wno-long-long -Wstrict-prototypes -Werror \
         -O -mno-avx -Dx64 -DPM
  # change this to suit your machine

* edit the ./build/include/global.h file. It is a copy of the openQCD-1.2 global.h
  file and the follwing lines need to be adjusted to your geometry:

  #define NPROC0 2
  #define NPROC1 2
  #define NPROC2 2
  #define NPROC3 1

  #define L0 16
  #define L1 8
  #define L2 8
  #define L3 16

  #define NPROC0_BLK 2
  #define NPROC1_BLK 2
  #define NPROC2_BLK 2
  #define NPROC3_BLK 1

  #define NAME_SIZE 128

* Switch back to ./build, type: make clean

* type: make

* ./build/mesons is the correlation measurement program
