To use build.sh to compile SyclParallelSTL with ComputeCpp:

  ./build.sh [--no-download] "path/to/ComputeCpp"
  (the path to ComputeCpp can be relative)

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


To use build.sh to compile SyclParallelSTL with triSYCL:

  ./build.sh [--no-download] --trisycl [-DTRISYCL_INCLUDE_DIR=path/to/triSYCL/include] [-DBOOST_COMPUTE_INCLUDE_DIR=path/to/boost/compute/include]

  For example (Ubuntu 16.04):
  ./build.sh --trisycl -DTRISYCL_INCLUDE_DIR=~/triSYCL/include -DBOOST_COMPUTE_INCLUDE_DIR=~/compute/include


The "--no-download" option is used to skip the cloning or pulling of
the GoogleTest git repository.
