pywlroots wheel contains unnecessary libs

[heuer]

I updated my project to pywlroots 0.16.7 and got the following error:

DRI driver not from this Mesa build ('24.0.5' vs '23.1.4')
failed to bind extensions

Extension modules: _cffi_backend (total: 1)

Installing from the source package works:

pip install --no-binary :all: pywlroots

The reason for the above mentioned error is, that the wheel provides libs which do not necessarily match the host machine:

Solution: Remove the libs from the wheel.

[heuer]

Hmmm... I looked at the previous releases: pywlroots always had the "libs" directory with the libraries... Strange that this wasn't a problem for my installation before.

[heuer]

The pywlroots-0.16.7-cp311-cp311-linux_aarch64.whl comes w/o the libs.

It just contains the _ffi.abi3.so (in the wlroots directory):

So, I wonder why other wheels ship with the libs

[heuer]

pywlroots 0.16.8 has the same problem. I cannot install pywlroots with pip unless I explicitly specify that the source code package should be used because the shipped libraries in the /lib subdirectory are incompatible with my system. And libraries like "libsystemd" or "libselinux" have nothing to do with the function of wlroots/pywlroots.

Aside from the fact that the libraries may be incompatible with the host system, this could also pose legal problems since pywlroots is under the NCSA license, which may not apply to all libraries distributed with pywlroots.

Still relevant for 0.17
