#
#  Setup build environment
#
#  1) Setup cmake variable CMAKE_PREFIX_PATH to point to a root
#     directory that has ROCr header and ROCr, ROCt libraries
#     
#     export CMAKE_PREFIX_PATH="Path to ROCr Header and ROCr, ROCt libraries"
#     
#       e.g. export CMAKE_PREFIX_PATH=/opt/rocm/
#       e.g. export CMAKE_PREFIX_PATH=${HOME}/git/compute/out/ubuntu-16.04/16.04/
#
#  2) Make an new folder called build under root folder
#
#     mkdir build
#
#  3) Enter into folder of build, and run CMAKE to generate makefile
#     and make it
#
#     cd build
#     cmake  ..
#     make
#
#     @note: Add -DCMAKE_BUILD_TYPE=Debug       # if you want to build Debug
#     @note: Add -DCMAKE_PREFIX_PATH="Rocm Dir" # if you don't define Env var
#
