mkl.h no such file or directory

Hello,
I'm interested in compiling some code to be compatible with intel MKL. 
The code I'm compiling is Trilinos.

I've set my variables with vars.sh

I'm using cmake with the following options related to the MKL tool. 

-DPardiso_MKL_LIBRARY_DIRS="/opt/intel/oneapi/mkl/2024.0/lib" \
-DTPL_ENABLE_MKL=ON \
-DTPL_MKL_LIBRARIES="-qmkl=parallel;-static-intel" \
-DTPL_MKL_INCLUDE_DIRS="$MKLROOT/include" \
-DTPL_ENABLE_PARDISO_MKL=ON \
-DTPL_PARDISO_MKL_LIBRARIES="-qmkl=parallel;-static-intel" \
-DTPL_PARDISO_MKL_INCLUDE_DIRS="$MKLROOT/include" \
-DAmesos_ENABLE_PARDISO_MKL=ON \
-DTPL_BLAS_LIBRARIES="-qmkl=parallel;-static-intel" \
-DTPL_BLAS_INCLUDE_DIRS="$MKLROOT/include" \
-DTPL_LAPACK_LIBRARIES="-qmkl=parallel;-static-intel" \
-DTPL_LAPACK_INCLUDE_DIRS="$MKLROOT/include" \
-m64 -Wl,--start-group ${MKLROOT}/lib/intel64/libmkl_intel_ilp64.a ${MKLROOT}/lib/intel64/libmkl_intel_thread.a ${MKLROOT}/lib/intel64/libmkl_core.a ${MKLROOT}/lib/intel64/libmkl_blacs_openmpi_ilp64.a -Wl,--end-group -liomp5 -lpthread -lm -ldl \

The last line is generated from the Intel® oneAPI Math Kernel Library (oneMKL) Link Line Advisor v6.23 .

When I try to make the program I get this error in one of the .cpp files. 
fatal error: mkl.h: No such file or directory
# include <mkl.h>

Any help would be greatly appreciated.

Thanks,
Eddy

Hi,

1. Could you please try once with oneAPI setvarsh.sh instead of the varsh.sh just to make sure all the necessary dependencies are in the path.
2. Also, could you please also set the following compiler option:

 -DMKL_ILP64 -I"${MKLROOT}/include"

Hi,
Thanks for getting back to me. I figured out the issue. My program required some library files, which were not downloaded. I needed to do 
yum install -y intel-oneapi-mkl-devel

Afterwards, I no longer ran into this issue.

Thanks for the update.
