[petsc-dev] building with MKL

[Mark Adams]

Stuck again. I use:


'--with-blaslapack-dir=/opt/intel/compilers_and_libraries_2018.1.163/linux/mkl/lib/intel64',

'--with-mkl_pardiso-dir=/opt/intel/compilers_and_libraries_2018.1.163/linux/mkl/lib/intel64',

It does not find the MKL library because, apparently, it is not
libmkl_intel.a (log file attached).

If I add:

    '--with-blaslapack-lib=libmkl_intel_thread.a',

I get:

Specify either "--with-blaslapack-dir" or "--with-blaslapack-lib
--with-blaslapack-include". But not both!
