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

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:
This has been fixed on x86_64 bit linux systems, thanks for pointing it out!
Additionally, shared libraries are now properly built by default, and the
BUILD_SHARED_LIBS option should be visible when building using a
CMake GUI front-end.

Testing with revision 2631. Looks like a stray ";" was introduced in front of
the -fPIC:
cd /builddir/build/BUILD/netcdf-4.2.1/build/libsrc && /usr/lib64/ccache/gcc
-DCURL_STATICLIB=1 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions

CMakeFiles/netcdf3.dir/v1hpg.c.o -c
/builddir/build/BUILD/netcdf-4.2.1/libsrc/v1hpg.c
This fixes it:

Still present in 2650, but needed a new patch:
