How to use LAPACK and BLAS for Julia 1.6.1 in UBUNTU 20.04

I am getting the following error while trying to run the Extrusion function in the Gmsh package through Julia API:
Error : LU factorization and substitution requires LAPACK

I think in my system, Julia cannot initiate the LAPACK package (also BLAS) on its own, or else, LAPACK and BLAS are not there at all in the system. Please help in this regard.

It sounds like the gmsh library/binary being installed by Gmsh.jl is not linked with LAPACK. (This error is coming from gmsh, not from Julia — Julia itself is always linked with LAPACK.)
