========================================================================
I. Managing Warnings
========================================================================
Compiler warnings are managed by setting the compiler flags variables.
Autotools uses the H5_CFLAGS and H5_CXXFLAGS, both variables set the flags nearly
identical, along with H5_FCFLAGS for Fortran. Autotools uses the type
and version of the compiler to determine which warning flags are used.
However, there is an option, enable-developer-warnings, to enable extra
flags for developers.
CMake uses the CMAKE_C_FLAGS and CMAKE_CXX_FLAGS, both sets are nearly
identical, along with CMAKE_Fortran_FLAGS for Fortran. CMake has a
minimum set of flags for GNU type compilers and for MSVC compilers. In
addition, CMake breaks the list of flags into groups. The groups for
GNU are roughly associated with the version of the compiler, while
the MSVC groups are associated with the warning levels for the
Microsoft compilers. The CMake option for enabling extra developer
warnings is HDF5_ENABLE_DEV_WARNINGS.
Custom settings can be used by setting;
Environment variables H5_CFLAGS and H5_CXXFLAGS for Autotools
CMake defines CMAKE_C_FLAGS and CMAKE_CXX_FLAGS for CMake
