Version 1.12.1

This release fixes issues related to the prefix directory inside of the pkg-config files which affected maintainer builds (Linux and FreeBSD package), the package manager Spack, or people using pkg-config to determine build/linker flags. In addition, some presets are made to smooth maintainer builds under FreeBSD.

IMPROVEMENTS / CHANGES

• Building samples: detect Intel MKL (when installed by a package manager).
• Improved build system under FreeBSD (detect BLAS library, etc).

FIXES

• Issue #331, issue #333, issue #334, and spack/spack#11413.
• OpenMP build issue in one of the code samples (GCC 9.1).
