Re: [netcdf-porting] [netcdfgroup] CMake integration with NetCDF

The CMake-integrated source code is not yet part of an official release,
but it may be
checked out from our public subversion repository:

svn checkout http://svn.unidata.ucar.edu/repos/netcdf/trunk netcdf

CMake 2.8.8+ is required. CMake may be downloaded from
http://www.cmake.org.  Instructions
for building NetCDF-C with CMake are described in the
'COMPILE_CMAKE.txt' file found in
the root NetCDF-C directory, or at

http://www.unidata.ucar.edu/software/netcdf/CompileCMake.html.



Looks like some issues with not using -fPIC on x86_64:
