project (HDF5_CPP_TEST CXX)

# --------------------------------------------------------------------
# Notes: When creating unit test executables they should be prefixed
# with "cpp_". This allows for easier filtering of the test suite when
# using ctest. An example would be
#  ctest -R cpp_
# which would only run the C++ based unit tests.
