ENH: Add patch step for add_external_project The patch step runs parallel to the update step since it does not make sense to have both. Configuration of the step requires specification of a PATCH_COMMAND argument to add_external_project.

ENH: Allow lists in AddExternalProject arguments The add_external_project function separates its arguments with ';' separators, so previously no command line argument could contain one. When specifying CMAKE_ARGS, some -D argument values may need to contain a semicolon to form lists in the external project cache. This adds add_external_project argument LIST_SEPARATOR to specify a list separator string. The separator is replaced by ';' in arguments to any command created to drive the external project. For example: add_external_project(... LIST_SEPARATOR :: CMAKE_ARGS -DSOME_LIST:STRING=A::B::C ...) passes "-DSOME_LIST:STRING=A;B;C" to CMake for the external project.
