This package is for the pykms bindings for kms++. It requires you to already have kms++-utils installed on your system.
These instructions are designed for use in a python virtual environment. If you are using the system python then it is simpler to install the system apt package for pykms (eg sudo apt install python3-kms++).
The default installations instructions, which should work in all cases (as of 29/09/2023) are:
sudo apt install -y libkms++-dev libfmt-dev libdrm-dev
pip install pykms
If you're building your own version of kms++ to be more up to date than your system release, then you may need to pass the repository and revision into meson. The arguments to do this are -C setup-args="-Drepository=https://my.repository.git" for the repository and -C setup-args="-Drevision=branch" for the revision. These are passed directly into git clone and git checkout respectively, so and strings that work with those will work here. The -C, --config-settings argument require an up to date version of pip>=23.1 so you may first need to run pip install --upgrade pip
You may also need to create a custom pypatch.patch, but at that point it is probably simpler to just clone the entire repository, edit the patch locally, and install the local folder with pip install ./pykms/. If you really want then your custom patch can be passed in with -C setup-args="-Dpatch=/home/me/mypatch.patch" - this will need an absolute path as the pip build will run in a temporary directory, so a relative path will not work.
