Possible nc-config new option

[gsjaardema]

I was recently helping someone with a program that linked to the netCDF library and they were having issues due to incompatible compilers and finding correct paths and libraries. I showed them nc-config and that helped quite a bit.

However, they were using C++ instead of C for their application, so they had to get the output from nc-config --cc and then look in that path and see if there was a C++ compiler and then paste that path into their compile line.

So... Would it make sense for nc-config to also have a --c++ option or --cxx which would print the path to the C++ compiler that the CMake build process for netCDF found during the configuration?

I don't think the C++ flags would be needed since they aren't compiling netCDF, only linking with it...

I'm not totally sold on the idea yet, but it would have saved a few confusing steps for the user in this case. I do see that there is already a --cxx option which doesn't echo anything (unless maybe the netCDF C++ library is also installed?)

Comments?

I'll get this in for the next release, and having a flag that works absent the (outdated) C++ library makes a lot of sense!
