# - Find the MAGMA library
# - Based on https://github.com/bravegag/eigen-magma-benchmark
#
# Usage:
#   find_package(MAGMA [REQUIRED] [QUIET] )
#
# It sets the following variables:
#   MAGMA_FOUND               ... true if magma is found on the system
#   MAGMA_LIBRARY_DIRS        ... full path to magma library
#   MAGMA_INCLUDE_DIRS        ... magma include directory
#   MAGMA_LIBRARIES           ... magma libraries
#
# The following variables will be checked by the function
#   MAGMA_USE_STATIC_LIBS     ... if true, only static libraries are found
#   MAGMA_ROOT                ... if set, the libraries are exclusively searched
#                                 under this path

#If environment variable MAGMA_ROOT is specified, it has same effect as MAGMA_ROOT
