Meson build file failing

[aradi]

The meson.build file in config/, especially line 106:

multicharge/config/meson.build

Line 106 in 4281891

if libs[0].startswith('-L')

seems to be fragile and breaks if no value had been provided for custom_libraries. I am not sure, probably, that variable should always have a defined value, when the code reaches that line, still a more informative error message would be helpful for the user. (Currently, it stops with [...]config\meson.build:106:13: ERROR: Index 0 out of bounds of array of size 0.)
