Yes ok, lib "rt" is not available on MacOS.
You could try to edit the certi/test/utility/CMakeLists.txt and replace

IF(WIN32)
    TARGET_LINK_LIBRARIES(CertiProcessus_B CERTI HLA)
ELSE(WIN32)
    TARGET_LINK_LIBRARIES(CertiProcessus_B CERTI HLA rt)
ENDIF(WIN32)

with something like

TARGET_LINK_LIBRARIES(CertiProcessus_B CERTI HLA)

IF (NOT APPLE)
    TARGET_LINK_LIBRARIES(CertiProcessus_B rt)
ENDIF(NOT APPLE)

If it works I'll try a better fix using something like

find_library(RT_LIBRARY rt) etc...
