Since lists are ;-separated one can just do
string(REPLACE ";" "${mysep}" concatenated "${list}") |

This is better discussed on the mailing list first. Resolving as "suspended" for now.

Without some sort of non-trivial additional processing, string(REPLACE) mishandles items with (escaped) ';'s in them.
Consider:
set(items
hello
"the\;world"
is on fire
)
string(REPLACE ";" " " replace_quoted "${items}")
message(STATUS "replace quoted: '${replace_quoted}'")
string(REPLACE ";" " " replace_list ${items})
message(STATUS "replace list: '${replace_list}'")
set(join_items)
foreach(item ${items})
if(join_items)
set(join_items "${join_items} ${item}")
else()
set(join_items "${item}")
endif()
endforeach()
message(STATUS "join items: '${join_items}'")
set(join_list)
foreach(item IN LISTS items)
if(join_list)
set(join_list "${join_list} ${item}")
else()
set(join_list "${item}")
endif()
endforeach()
message(STATUS "join list: '${join_list}'")
...both of the tries using string(REPLACE) give a result other than is desired (and different from each other, as well). The versions using foreach both give the desired result. |

Actually, the other main reason I would like this is to do things like:
join(output ", "
"item1"
"item2"
...
)
...which is how I am using it in the most recent project. |
