HASS: libturbojpeg switch to libjpeg-turbo

home-assistant/docker#313

Currently, (using libturbojpeg), HASS can't seem to find libturbojpeg when using a camera entity:

2024-07-15 15:40:01.067 ERROR (MainThread) [homeassistant.components.camera.img_util] Error loading libturbojpeg; Camera snapshot performance will be sub-optimal

Already reported here #988. As I mentioned I'm not sure what the fix could be.

Sorry for the duplicate, I misunderstood the upstream issue. Thanks for the link

Did a bit of digging, PyTurboJPEG just doesn't look in the location of the alpine package.

Short term fix: add LD_LIBRARY_PATH=/usr/lib env for HASS container
Long term fix: lilohuang/PyTurboJPEG#79

No fix from this repo required

Small followup - found another alternative while chasing a different lib issue

Alpine linux causes problems with the python ctypes.utils.find_library() function, which many packages use. Eg, HASS also can't find libpcap for the same reason

find_library() attempts to use several tools, the one that works in Alpine Linux seems to be ld, it includes /usr/lib by default. But it only finds libraries symlinked to /usr/lib/*.so, which ONLY happens in -dev packages

Basically, if we add binutils for ld and -dev versions of lib packages for the symlink, LD_LIBRARY_PATH=/usr/lib is not necessary.

quick diff that fixes missing libturbojpeg and libpcap:
