Summary of Issue

I'm working on integrating SEACAS-Exodus with a code I am working on. However, when we install NetCDF using CMake, then the cmake config files are installed as

lib/cmake/netCDF/netCDFConfig.cmake
lib/cmake/netCDF/netCDFConfigVersion.cmake
lib/cmake/netCDF/netCDFTargets-debug.cmake
lib/cmake/netCDF/netCDFTargets.cmake

However, SEACAS-Exodus calls find_package(NetCDF). This triggers a search for NetCDFConfig.cmake and netcdf-config.cmake. On case sensitive file systems this fails. If you switched to the all lower-case version, this should remediate this confusion and maintain backwards compatibility.

Steps to reproduce the behavior

Install NetCDF4 and then call CMake for the SEACAS-Exodus distribution something like:

cmake -DSEACASProj_ENABLE_SEACASExodus:BOOL=ON \
   -DSEACASProj_ENABLE_SEACASExodus_for:BOOL=ON \
   -DCMAKE_INSTALL_PREFIX:PATH=${TPL_DIR}/Install/SEACASExodus \
   -DSEACASProj_ENABLE_TESTS:BOOL=ON -DBUILD_SHARED_LIBS:BOOL=OFF \
   -DTPL_ENABLE_Netcdf:BOOL=ON -DTPL_ENABLE_MPI:BOOL=OFF \
   -DSEACASExodus_ENABLE_THREADSAFE:BOOL=OFF \
   -DNetCDF_DIR:PATH=${TPL_DIR}/Install/netCDF-4/lib/cmake/netcdf \
   -DHDF5_NO_SYSTEM_PATHS:BOOL=ON \
   -DSEACASProj_SKIP_FORTRANCINTERFACE_VERIFY_TEST:BOOL=ON \
   /path/to/seacas-exodus-src

Also, would a PR for my proposed change be welcome? i.e., netcdf-config.cmake
