# CBLAS_FOUND Boolean holding whether or not the Netlib BLAS library was found
# CBLAS_INCLUDE_DIRS The Netlib BLAS include directory
# CBLAS_LIBRARIES The Netlib BLAS library
#
# In case BLAS is not installed in the default directory, set the CBLAS_ROOT variable to point to
# the root of BLAS, such that 'cblas.h' can be found in $CBLAS_ROOT/include. This can either be
# done using an environmental variable (e.g. export CBLAS_ROOT=/path/to/BLAS) or using a CMake
# variable (e.g. cmake -DCBLAS_ROOT=/path/to/BLAS ..).
