To use build.sh to compile sycl-blas with ComputeCpp:

  ./build.sh "path/to/ComputeCpp"
  (the path to ComputeCpp can be relative)

  For example:
  ./build.sh /home/user/ComputeCpp


To use build.sh to compile sycl-blas with a specific blas installation (e.g. OpenBLAS):

  ./build.sh "path/to/ComputeCpp" "path/to/blas"

  For example:
  ./build.sh /home/user/ComputeCpp /tmp/OpenBLAS/build
