# Synopsis:
#
# add_options (lang build opts)
#
# where:
#
# lang Name of the language whose compiler should receive the
# options, e.g. CXX. If a comma-separated list is received
# then the option is added for all those languages. Use the
# special value ALL_LANGUAGES for these languages: CXX, C
# and Fortran
#
# build Kind of build to which this options should apply,
# such as DEBUG and RELEASE. This can also be a comma-
# separated list. Use the special value ALL_BUILDS to apply
# to all builds.
#
# opts List of options to add. Each should be quoted.
#
# Example:
#
# add_options (CXX RELEASE "-O3" "-DNDEBUG" "-Wall")
