Error when building in codespaces

Reproduce the failure with meson setup --buildtype release builddir followed by meson compile in the reported environment. Inspect meson.build and the source path associated with resolve_qsort_Float16; the work is done when the shared library links successfully without the undefined fp16_icl::qsort symbol.

Hi,

Please see below.

Thank you in advance for your help.
