The primary fix is to improve CMake build support. Specific changes include: * CMake: Provide a better soln to locating the AWS SDK libraries; the new way is the preferred method as described in the aws-cpp-sdk documentation. * CMake (and Automake): allow -DENABLE_S3_SDK (default off) to suppress looking for AWS libraries. * CMake: add the complete set of nczarr tests * CMake: add EXTERNL as needed to various .h files. * Improve support for windows drive letters in paths. * Add nczarr and s3 flags to nc-config * For VisualStudio X nczarr, cleanup the NAN+INFINITY handling * Convert _MSC_VER -> _WIN32 and vice versa as needed * NCZarr - support multiple platform paths including windows, cygwin. mingw, etc. * NCZarr - sort the test outputs because different platforms produce directory contents in different orders. One big change concerns netcdf-c/CMakeLists.txt and netcdf-c/configure.ac. In the current versions, it was the case that --disable-hdf5 disabled netcdf-4 (libsrc4). With nczarr, this can no longer be the case because nczarr requires libsrc4 even if libhdf5 is disabled. So, I modified the above files to move the format options (HDF5, NCZarr, HDF4, etc) to a single place near the front of the files. Now it is the case that: * Enabling any of the formats that require libsrc4 also does an implicit --enable-netcdf4. * --disable-netcdf4 | --disable-netcdf-4 now becomes and alias for --disable-hdf5. There are probably some bugs in this change in terms of dependencies between format options. Problems: * CMake S3 support is still not working for Visual Studio * A recent issue points out that there is work to do on handling UTF8 filenames, but that will be addressed in a separate fix. Notes: * Consider converting all of our includes/.h files to use EXTERNL
