I found a way of doing list-maps with generator expressions, by writing a generator expression to apply to each element, escaping the generator expression and feeding it through $<LIST:TRANSFORM> and $<GENEX_EVAL>:

Mapping lists in generator expressions

Ok, that works! Thank you. It even works recursively!: set(targets picolibc::picolibc ZLIB::ZLIB) function(escape_generator_expression var) string(REPLACE ">" "__ANGLE_R__" ${var} "${${var}}") string(REPLACE "$" "$<1:$>" ${var} "${${var}}") string(REPLACE "," "$<COMMA>" ${var} "${${var}}") string(REPLACE "__ANGLE_R__" "$<ANGLE-R>" ${var} "${${var}}") return(PROPAGATE ${var}) endfunction() set(prop "INTERFACE_INCLUDE_DIRECTORIES") set(get_prop "$<TARGET_PROPERTY:\\1,${prop}>…
