The library libslate_scalapack_api.so uses some environment variables

to make decisions that are not available in the ScaLAPACK
parameters.

* SLATE_SCALAPACK_TARGET HostTask (default), Devices, HostNest, HostBatch (case indifferent)
* SLATE_SCALAPACK_VERBOSE 0,1 (0: no output, 1: print some minor output)
* SLATE_SCALAPACK_PANELTHREADS integer (number of threads to serve the panel, default (maximum omp threads)/2 )
* SLATE_SCALAPACK_IB integer (inner blocking size useful for some routines, default 16)
* SLATE_SCALAPACK_LOOKAHEAD integer (lookahead number of panels, default 1)

Example on a properly configured SLATE install on a machine with GPUs.
