# Detect SuiteSparse libraries:
# Either tell Hunter to provide SuiteSparse for you or manually
# define where SuiteSparse and LAPACK can be found.
# To activate Hunter use the following commandline
# cmake -S . -B _build -DHUNTER_ENABLED=ON
#
# In the manual case, if not found automatically, set SuiteSparse_DIR
# in CMake to the directory containing suitesparse-config.cmake located
# in the installed directory.
# for example use the following command line
# cmake -S . -B _build -DSuiteSparse_DIR=../../_install/lib/cmake/suitesparse-5.1.0
