+## Scalapack
+
+added in **0.53.0**:
+
+```meson
+scalapack = dependency('scalapack')
+```
+
+Historically and through today, typical Scalapack setups have broken and incomplete pkg-config or
+FindScalapack.cmake. Meson handles finding Scalapack on setups including:
+
+* Linux: Intel MKL or OpenMPI + Netlib
+* MacOS: Intel MKL or OpenMPI + Netlib
+* Windows: Intel MKL (OpenMPI not available on Windows)

+
+Let Michael know if there are more MKL / Lapack / compiler combination you want.
+Refer to https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor
+
+Finds SCALAPACK libraries for MKL, OpenMPI and MPICH.
+Intel MKL relies on having environment variable MKLROOT set, typically by sourcing
+mklvars.sh beforehand.
+
+Parameters
+^^^^^^^^^^
+
+``MKL``
+  Intel MKL for MSVC, ICL, ICC, GCC and PGCC. Working with IntelMPI (default Window, Linux), MPICH (default Mac) or OpenMPI (Linux only).
+
+``IntelMPI``
+  MKL BLACS IntelMPI
+
+``MKL64``
+  MKL only: 64-bit integers  (default is 32-bit integers)
+
+``OpenMPI``
+  SCALAPACK + OpenMPI
+
+``MPICH``
+  SCALAPACK + MPICH
+
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+``SCALAPACK_FOUND``
+  SCALapack libraries were found
+``SCALAPACK_<component>_FOUND``
+  SCALAPACK <component> specified was found
+``SCALAPACK_LIBRARIES``
+  SCALapack library files
+``SCALAPACK_INCLUDE_DIRS``
+  SCALapack include directories
