To me it looks like in the first call all of this stuff:
Multifield_Repartition;SOURCES;multifield_repartition.cpp;COMM;mpi;serial;STANDARD_PASS_OUTPUT;NUM_MPI_PROCS;4;FAIL_REGULAR_EXPRESSION;TEST 
FAILED;PASS_REGULAR_EXPRESSION;TEST 
PASSED;ARGS;--num_particles=50;--num_dimensions=2

is crammed into one variable.

It might be clearer if you changed your messages to do this:
   MESSAGE("FINAL EXE_NAME: ${EXE_NAME}")
   MESSAGE("FINAL ARGV: ${ARGV}")
   MESSAGE("FINAL ARGN: ${ARGN}")

Most likely it was called quoted?

my_func("lots of stuff;foo;bar")
vs
my_func("lots of stuff" foo bar)
