CMake messages on checking the NetCDF4 chunking constants are not shown on some E3SM machines

[dqwu]

With PR #536 (Configure check for NC4 chunking consts), the following CMake messages are expected when we configure SCORPIO with NetCDF4 support:

-- Checking Whether the NetCDF4 chunking constants are available
-- Checking Whether the NetCDF4 chunking constants are available - [yes or no]

These messages are not shown on a few E3SM machines so far, including Chrysalis and Summit.

Simple steps to reproduce this CMake issue on Chrysalis:

module purge 
module load cmake/3.24.2-whgdv7y intel/20.0.4-kodw73g openmpi/4.1.3-pin4k7o

git clone https://github.com/E3SM-Project/scorpio.git
cd scorpio

mkdir build
cd build

CMake outputs related to NetCDF do not contain messages on checking the NetCDF4 chunking constants:

For comparison, the expected messages are shown on ANL GCE nodes:

...
-- NetCDF Fortran library dependencies: ****
-- Checking Whether the NetCDF4 chunking constants are available
-- Checking Whether the NetCDF4 chunking constants are available - yes
-- Disabling support for PnetCDF
...

This is a known issue that we need to fix later - the current PR #536 should be OK to be merged.
