%global _description %{expand:
HighFive is a modern header-only C++11 friendly interface for libhdf5.

HighFive supports STL vector/string, Boost::UBLAS, Boost::Multi-array, Eigen
and Xtensor. It handles C++ from/to HDF5 with automatic type mapping. HighFive
does not require additional libraries (see dependencies) and supports both HDF5
thread safety and Parallel HDF5 (contrary to the official hdf5 cpp)

It integrates nicely with other CMake projects by defining (and exporting) a
HighFive target.

Design:
- Simple C++-ish minimalist interface
- No other dependency than libhdf5
- Zero overhead
- Support C++11

Feature support:
- create/read/write files, datasets, attributes, groups, dataspaces.
- automatic memory management / ref counting
- automatic conversion of std::vector and nested std::vector from/to any
  dataset with basic types
- automatic conversion of std::string to/from variable length string dataset
- selection() / slice support
- parallel Read/Write operations from several nodes with Parallel HDF5
- Advanced types: Compound, Enum, Arrays of Fixed-length strings, References
  etc... (see ChangeLog)

# Does not build on 32 bit architectures

# Partially patched, fixing i686; see upstream bug for armv7hl status. We can
# work around this by disabling OpenCV on armv7hl until a patch is available.
