WRF Hydro Coupled fails to build without specific paths added

[William.Hatheway]

When building WRF Hydro Coupled following the NCAR's build guide located here:

APPENDICES — WRF-Hydro Modeling System 5.4.0 documentation

It fails to build with intel llvm compilers.

Steps to reproduce:

1. Install the required libraries
2. download the wrf-hydro 5.4 github (git clone GitHub - NCAR/wrf_hydro_nwm_public: WRF-Hydro model code)
3. download WRF 4.7.1 in new folder ( git clone GitHub - wrf-model/WRF: The official repository for the Weather Research and Forecasting (WRF) model -> cd WRF -> git submodule update --init --recursive )
4. remove hydro folder from wrf folder based on users guide and then copy WRF hydro src folder to new hydro folder ( rm -r

   "${WRF_FOLDER}"/WRF-${WRF_VERSION}/hydro/cp -r "${WRF_FOLDER}"/Hydro-Basecode/wrf_hydro_nwm_public/src "${WRF_FOLDER}"/WRF-${WRF_VERSION}/hydro

5. configure ( ./configure_new -x -p "oneAPI LLVM" -- -DWRF_CORE=ARW -DWRF_NESTING=BASIC -DWRF_CASE=EM_REAL -DUSE_MPI=ON -DUSE_PIO=ON -DENABLE_HYDRO=ON -DWRF_HYDRO_NUDGING=1 -DUSE_HDF5=${HDF5_ROOT} -DUSE_JASPER=${Jasper_ROOT} 2>&1 | tee wrf_configure_new.log)
6. compile ( ./compile_new -j 2 2>&1 | tee compile.wrf1.log)
7. Build will fail at fftpack5

Now this is what I don't understand, when I export the netcdf include and lib paths the compilation will build.

export FFLAGS="-I${NETCDF_ROOT}/include ${FFLAGS}"
  export FCFLAGS="-I${NETCDF_ROOT}/include ${FCFLAGS}"
  export LDFLAGS="-L${NETCDF_ROOT}/lib    ${LDFLAGS}"

why is this?

@islas any ideas why the include and lib paths aren't being added to the cmake commands?
