message(STATUS "TO CHECK: " ${PROG_SRC})
is equivalent to message(STATUS "TO CHECK: " "main.cpp" "version.cpp")
message() concatenates the parameters so your message is "TO CHECK: 
main.cppversion.cpp".

To prevent the PROG_SRC content from being split when expanding you can 
use quotes around the expansion:
     message(STATUS "TO CHECK: ${PROG_SRC}")

When you pass ${PROG_SRC} the expansion will split at semicolon again so 
your two list item become two arguments.
SOURCE_LIST only covers the first. You can either quote the expansion 
again or use e.g. ${ARGN} to access a variable number of arguments past 
the given list.
