+Subject: [PATCH] Fix tests for out-of-source builds
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When the build directory is not _under_ the source directory then
+flake8 cannot find the local config file and it will try to check
+piper.in which fails per 1ed66262b77ebd9fe188894d36842527da39508a
+
+To fix this I propose to
+
+1. pass the config to flake8 explicitly
+2. remove piper.in from the args list since it is excluded in the
+   flake8 config anyway
+3. check the generated $build/piper.devel and $build/piper too per
+   1ed66262b77ebd9fe188894d36842527da39508a
+4. merge the --ignore in meson.build with the config
+
+Steps to reproduce:
+
+```
+$ meson ../build
+$ ninja -C../build test
+...
