If you really need this, then patches are welcome. The only known way is
|
||
|
|
to create a dummy C++ file in the meson-private directory and adding
|
||
|
|
that to the target's source list when needed. The primitives exist
|
||
|
|
but may need some tweaking. Grep for language_stdlib_only_link_flags to find
|
||
|
|
where this is handled in other backends.''')
