In our VTK/ParaView dashboards we ensure the submit happens by doing
partial submissions after each stage (this also gives incremental results
on CDash):
set(success TRUE)
ctest_configure(RETURN_VALUE configure_result)
ctest_submit(PARTS Configure) # Tell submit to submit a partial result with
only the configure step
if (configure_result)
message("Configure failed")
set(success FALSE)
# you could exit here
endif()
if (success)
... # run next stage here
