+# - Find BLAS EXTENDED for MORSE projects: find include dirs and libraries
+#
+# This module allows to find BLAS libraries by calling the official FindBLAS module
+# and handles the creation of different library lists whether the user wishes to link
+# with a sequential BLAS or a multihreaded (BLAS_SEQ_LIBRARIES and BLAS_PAR_LIBRARIES).
+# BLAS is detected with a FindBLAS call then if the BLAS vendor is Intel10_64lp, ACML
+# or IBMESSLMT then the module attempts to find the corresponding multithreaded libraries.
+#
+# The following variables have been added to manage links with sequential or multithreaded
+# versions:
+# BLAS_INCLUDE_DIRS - BLAS include directories
+# BLAS_LIBRARY_DIRS - Link directories for BLAS libraries
+# BLAS_SEQ_LIBRARIES - BLAS component libraries to be linked (sequential)
+# BLAS_PAR_LIBRARIES - BLAS component libraries to be linked (multithreaded)
