Describe the bug
config/meson.build
and
subprojects/multicharge/config/meson.build

on line 110 have

libs = get_option('custom_libraries')

• if libs[0].startswith('-L')

There is no check here on the size of the libs array. on HPE/Cray systems generally the relevant libraries are handled by the cc/ftn wrapper scripts rather than given explicitly on the command line, so the size of libs can be zero.

This results in the if statement attempting to access element 0 of a size zero array, and the meson script fails.

To Reproduce
Attempt to build using meson where libs would be size 0

Expected behaviour
Meson does not give an error and the build proceeds
