How to install Tensor extension dependencies on Linux

[bounmed]

I got three errors when trying to install the tensor package using pecl.
Error 1:
/tmp/pear/temp/tensor/ext/tensor.c:25:10: fatal error: cblas.h: No such file or directory
Error 2:
/tmp/pear/temp/tensor/ext/include/linear_algebra.c:7:10: fatal error: lapacke.h: No such file or directory
Error 3:

/usr/bin/ld: cannot find -lgfortran
collect2: error: ld returned 1 exit status

The solution is to install libopenblas, libraries and gfortran.

apt-get install libopenblas-dev
apt-get install liblapacke-dev
apt-get install gfortran

Thank you but we already have instructions to install Tensor extension dependencies in the README!
