How about the following two examples for a table or 2d array.
In the first one, each column can have a name too. Its like an array of
pointers in C++.
set(fruits apple orange banana)
set(animals cat dog elephant)
set(columns fruits animals)
foreach(column ${columns})
foreach(item ${${column}})
message("${column} has item ${item}")
endforeach()
endforeach()
Or if you have pairs, one fruit with one animal
set(tuples
"apple\;cat"
"orange\;dog"
"banana\;elephant"
)
foreach(pair ${tuples})
message("pair has items ${pair}")
foreach(component ${pair})
message("component = ${component}")
endforeach()
endforeach()
Both of those seem close enough to 2d array functionality using the cmake
language.
