| # - Find HDF5, a library for reading and writing self describing array data. |
| # |
| # This module invokes the HDF5 wrapper compiler that should be installed |
| # alongside HDF5. Depending upon the HDF5 Configuration, the wrapper compiler |
| # is called either h5cc or h5pcc. If this succeeds, the module will then call |
| # the compiler with the -show argument to see what flags are used when compiling |
| # an HDF5 client application. |
| # |
| # The module will optionally accept the COMPONENTS argument. If no COMPONENTS |
| # are specified, then the find module will default to finding only the HDF5 C |
| # library. If one or more COMPONENTS are specified, the module will attempt to |
| # find the language bindings for the specified components. Currently, the only |
| # valid components are C and CXX. The module does not yet support finding the |
| # Fortran bindings. If the COMPONENTS argument is not given, the module will |
| # attempt to find only the C bindings. |
| # |
| # On UNIX systems, this module will read the variable HDF5_USE_STATIC_LIBRARIES |
| # to determine whether or not to prefer a static link to a dynamic link for HDF5 |
| # and all of it's dependencies. To use this feature, make sure that the |
| # HDF5_USE_STATIC_LIBRARIES variable is set before the call to find_package. |
| # |
| # To provide the module with a hint about where to find your HDF5 installation, |
| # you can set the environment variable HDF5_ROOT. The Find module will then |
| # look in this path when searching for HDF5 executables, paths, and libraries. |
| # |
| # In addition to finding the includes and libraries required to compile an HDF5 |
| # client application, this module also makes an effort to find tools that come |
| # with the HDF5 distribution that may be useful for regression testing. |
| # |
| # This module will define the following variables: |
| # HDF5_INCLUDE_DIRS - Location of the hdf5 includes |
| # HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated) |
| # HDF5_DEFINITIONS - Required compiler definitions for HDF5 |
| # HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings. |
| # HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings |
| # HDF5_LIBRARIES - Required libraries for all requested bindings |
| # HDF5_FOUND - true if HDF5 was found on the system |
| # HDF5_LIBRARY_DIRS - the full set of library directories |
| # HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support |
| # HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler |
| # HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler |
| # HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool |
