Hi Ward


 -DHAVE_MFHDF_H=<path>,


yes, that was exactly what I was looking for.
I am not very familiar yet with CMake scripts, all these symbols are listed in CMakeLists.txt, the location of the HDF4 multi file library, as well 
the HDF4 library names


CHECK_INCLUDE_FILE("mfhdf.h" HAVE_MFHDF_H)
FIND_LIBRARY(HDF4_DF_LIB NAMES df libdf)
FIND_LIBRARY(HDF4_MFHDF_LIB NAMES mfhdf libmfhdf)

I tried with these options, that for my case are

-D"HAVE_MFHDF_H=I:\hdf4_explorer\mfhdf\libsrc"
-D"HDF4_DF_LIB=I:\hdf4_explorer\windows\lib\debug\singlethreaded\hd421d.lib"
-D"HDF4_MFHDF_LIB=I:\hdf4_explorer\windows\lib\debug\singlethreaded\hm421d.lib"

The Cmake generation of projects ran without errors

However, when I opened the generated solution, I get a compiler error because the HDF4 header file still cannot be found by the compiler
2>J:\netcdf-c-4.3.1-rc3\include\nc4internal.h(32): fatal error C1083: Cannot open include file: 'mfhdf.h': No such file or directory 

this is the offending line

#ifdef USE_HDF4
#include <mfhdf.h>
#endif
By looking at the project settings, for example for the project 'netcdf4', these are the names included in the "Additional Include directories", under the "C++ "->"General" option 


J:/netcdf-c-4.3.1-rc3/build/libsrc4;J:/netcdf-c-4.3.1-rc3/libsrc4;I:/hdf5-1.8.11/src;I:/zlib-1.2.5;J:/curl-7.29.0/builds/libcurl-vc10-x86-debug-static-ipv6-sspi-spnego-winssl/include;J:/netcdf-c-4.3.1-rc3/include;J:/netcdf-c-4.3.1-rc3/oc2;J:/netcdf-c-4.3.1-rc3/libsrc;J:/netcdf-c-4.3.1-rc3/build;J:/netcdf-c-4.3.1-rc3/libsrc4/.;%(AdditionalIncludeDirectories)
As you can see the HDF5, zlib, curl locations are all there, but the HDF4 location is missing
A workaround for now is to add these locations manually, thanks for looking into this.

Hi Pedro,
It is complaining that it cannot find mfhdf.h; is this file present? If it is, then CMake should be locating it (assuming it is on the standard path); otherwise, if it is not on the standard path, you may need to pass the location to CMake using (I believe) -DHAVE_MFHDF_H=<path>, or by specifying the path using the 'CFLAGS' variable. I will look into this.

Is there a way that I can make the Cmake build detect the HDF4 headers and libraries ? 

I tried

$cd build
$cmake -C ../cmake/ConfigUser.cmake <all my previous options> -D"ENABLE_HDF4=ON"
where <all my previous options> are the options I used previously regarding HDF5, curl, etc. 

I got the error

--
-- Looking for mfhdf.h
-- Looking for mfhdf.h - not found
CMake Error at CMakeLists.txt:411 (MESSAGE):
 HDF4 Support specified, cannot find file mfhdf.h
I tried the 'NC_USE_STATIC_CRT' option and it generated the projects with the static CRTs, thank you for doing that.

Hello all,
On behalf of the netCDF-C development team, we are happy to announce the availability of the third release candidate for netCDF-C version 4.3.1.
Highlights of this release beyond the previous release candidate include: 

* netCDF-4 compilation with OpenMPI as an alternative to MPICH2.
* Addressed Parallel netCDF-4 hanging when using HDF5 1.8.10.
* Large File Support on Windows is now functional.
* A new option for CMake-based Visual Studio builds, 'NC_USE_STATIC_CRT', used to specify which type of CRT libraries to link against (shared being the default).
Source-code zip and tar.gz archives can be found at: http://github.com/Unidata/netcdf-c/releases/tag/v4.3.1-rc3
Complete release notes may be found at: http://www.unidata.ucar.edu/software/netcdf/docs_rc/release_notes.html
Pre-built Windows binaries are available from: http://www.unidata.ucar.edu/netcdf/docs_rc/winbin.html
We look forward to addressing any issues, questions or concerns which may arise from this release candidate. 

Thank you in advance,

-Ward
