Parallel iteration over lists in makefile or CMake file

Question

Is there a way to loop over multiple lists in parallel in a makefile or CMake file?

I would like to do something like the following in CMake, except AFAICT this syntax i

Answer 1

As of CMake 3.17, the foreach() loop supports a ZIP_LISTS option to iterate through two (or more) lists simultaneously:

set(a_values a0 a1 a2)
set(b_values b0 b1 b2)
foreach(a b IN ZIP_LISTS a_values b_values)
    message("${a} ${b}")
endforeach()

This prints:

a0 b0
a1 b1
a2 b2
