122 122 123 123 124 124 Notes: 125 * The ``ADIOS2_USE_HDF5`` option requires the use of a matching serial or parallel version depending on whether ``ADIOS2_USE_MPI`` is enabled. Similary, enabling MPI and Python bindings require ``mpi4py``. 126 125 127 * Optional ROOT suffix to a dependency can guide ``cmake`` into finding a particular dependency: 126 To provide search paths to CMake for dependency searching: 127 128 - Use a ``PackageName_ROOT`` variable to provide the location of a specific package. 129 - Add an install prefix to the ``CMAKE_PREFIX_PATH`` which is searched for all packages. 130 - Both the ``PackageName_ROOT`` and ``CMAKE_PREFIX_PATH`` can be used as either environment variables or CMake variables (passed via -D), where the CMake variable takes prescedence. 122 122 123 123 124 124 Notes: 125 * The ``ADIOS2_USE_HDF5`` option requires the use of a matching serial or parallel version depending on whether ``ADIOS2_USE_MPI`` is enabled.
