Issue with MKL in Kaldi

[alexmplata16]

After running install.sh i get this:

Warning: IRSTLM is not installed by default anymore. If you need IRSTLM
Warning: use the script extras/install_irstlm.sh
All done OK.

Configuring MKL library directory: ***configure failed: MKL libraries could not be found. Please use the switch --mkl-libdir or try another math library, e.g. --mathlib=ATLAS (would be slower) ***

what do i have to do? Because when i open env.sh this is what i found:

if [ $(which python) != /home/alejandro/Voice-Privacy-Challenge-2020/venv/bin/python ]; then source /home/alejandro/Voice-Privacy-Challenge-2020/venv/bin/activate; fi
