Installing from local build/dist fails

[mdxs]

As there are new features in the code repository after the Blatann v0.5.0 release, I've made a local build/dist (using make) and then tried to install that in another virtual environment on Linux; in my case Xubuntu 22.04.3 LTS Desktop amd64 (64-bit) within a VMware Guest.

However, I got the following error:

$ pip install ~/dev/gh/blatann/dist/blatann-0.5.0.tar.gz 
Processing /home/mdxs/dev/gh/blatann/dist/blatann-0.5.0.tar.gz
  Preparing metadata (setup.py) ... error

  note: This error originates from a subprocess, and is likely not a problem with pip.

Pointing at: https://github.com/ThomasGerstenberg/blatann/blob/8cf44c01c577e7b9fc6c92c3021bf6735c0660dd/setup.py#L13

That I read has the intention to ensure that requirements.txt is reflected in the setup.py dynamically.

However, that doesn't work when trying to install from the dist/blatann-0.5.0.tar.gz directly, as shown above.

Actually found that the following works fine:

So closing this issue, as I probably don't know about the build process ;-)
