# o2_add_test_root_macro generate a test for a Root macro.
#
# That test is trying to load the macro within a root.exe session using
# ".L macro.C"
#
# * arg COMPILE: if present we generate, in addition to the baseline "load
# the macro test", a test to compile the library, i.e. using ".L macro.C++
# * arg COMPILE_ONLY: if present we discard the "load the macro" test and
# only attempt the compilation test. It implies COMPILE
# * arg ENVIRONMENT: sets the running environment for the generated test(s).
# * arg PUBLIC_LINK_LIBRARIES: the list of targets this macro is depending on.
# Required to be able to specify correctly the include and library paths to
# test the (compiled version of) the macro.
# * arg LABELS: labels to be attached to the test. Note that the label "macro"
# is automatically applied by this function, and the label "macro_compiled"
# as well in case COMPILE is defined
