Am I referring variables in MACRO correctly? Why second version
prints correct length and the first - not?
Not entirely sure, but perhaps this is because (from the macro()
docs):
"Note that the parameters to a macro and values such as ARGN are not
variables in the usual CMake sense. They are string replacements much
like the c preprocessor would do with a macro. If you want true CMake
variables you should look at the function command."

If I do
MYTEST(something;new)
i.e. without the quotes, I get
Len: 2
Len: 1
I think in your example (where you use the quotes) the problem is that
argTemp IS a single string which gets literally replace at every
occurrence of argTemp as Tyler mentioned.
