[CMake] Passing lists to macros

[David Cole]

Try:
test("${L1}")

You are passing multiple arguments to the macro by using ${L1} without
double quotes (because it expands to a list with multiple elements). Using
double quotes makes it all go into the first macro argument...

Alternatively, you could look up the help for MACRO using:
cmake --help-command MACRO

and read up on using ARGN as a list of arguments past the formal macro
arguments...


HTH,
David
