Subject: [PATCH] Fix error in compat/CMakeList.txt

The `CMakeLists.txt` in `src/compat` was conditionally reusing the
variable `SOURCES` inherited from above, which contained relative paths
not related to this directory. This caused `target_sources` to generate
a warning.

This commit fixes this by setting `SOURCES` to be empty first in the
file.
