# This cmake module is meant to hold helper functions/macros
# that make maintaining the cmake build system much easier.
# This is especially helpful since gsl needs to provide coverage
# for multiple versions of cmake.
#
# Any functions/macros should have a gsl_* prefix to avoid problems

# Adding the GSL.natvis files improves the debugging experience for users of this library.
