Hi everyone, first time in the mailing list...

I was wondering if anybody is already working in a recipe for the package =
dlib pyhon3 module,
so far this is the recipe I've been working on
```bitbake
# python3-dlib_19.21.1.bb
SUMMARY =3D "A toolkit for making real world machine learning and data ana=
lysis applications"
HOMEPAGE =3D "https://pypi.python.org/pypi/dlib"

```


I'm not a bitbake or cmake expert, during do_compile() task i get the foll=

```

Not sure why the linker **gcc/aarch64-poky-linux/8.3.0/ld** is showing the=
 error
```
 error adding symbols: file in wrong format
```
Perhaps i'm messing things up with cmake-native environment but not sure h=
ow i can enable cmake to be used by setup.py if it is not with DEPENDS=3Dcm=
ake-native.

Any clue to solve this issue will be highly appreciated, or if you know wh=
o is already working on this it will be great to have its contact :)

Also i use dunfell branch for meta-oe
