Help: Add advice for dealing with semicolons in lists
Provide an inline example, and reference the ExternalProject LIST_SEPARATOR
option as another example.
Also update the LIST_SEPARATOR
documentation. Since CMAKE_ARGS
is used to construct the default CONFIGURE_COMMAND
for CMake-based external projects, the LIST_SEPARATOR
option works for it too.
Issue: #23315
Backport: release
