ctest-sac2c-with-variants.cmake

# This macro adds a recipe to compile a sac program using a variants file.
# Variants let someone generate several different code, via #ifdef.
#
# A variants file has the same name as the sac program, but 
# with the extension .variant, e.g. a variant file for a.sac would be a.variant.
#
# A variant file has the following syntax:
#       <suffix1>: <flags1>
#       ...
#       <suffixN>: <flagsN>
#
# This specifies that a sac program (e.g. a.sac) should build the following
# binaries:
#
#      a<suffix1>, a<suffix2>, ... a<suffixN>
#
# each a<suffixI> is built by calling:
#      sac2c <flagsI> -o a<suffixI>
#
# Arguments:
#     name:  
#           name of the sac file, relative to CMAKE_CURRENT_SOURCE_DIR
#     local_sac_modules:
#           a list of sac modules that should participate in dependency
#           resolution.  See cmake-common/resolve-sac2c-dependencies.cmake
#           for more details
#     sac2c_flags:
#           sac2c flags that are used when calling the sac2c compiler, for
#           each variant. E.g., -DAPL.
