Notably, ./build-tree/CMakeFiles/CMakeOutput.log says

implicit dirs: [/usr/lib/gcc/i686-gnu/8;/usr/lib/i386-gnu;/usr/lib;/lib/i386-gnu]

implicit dirs: [/usr/lib/gcc/x86_64-linux-gnu/8;/usr/lib/x86_64-linux-gnu;/usr/lib;/lib/x86_64-linux-gnu;/lib]

(I don't know what implicit dirs means exactly, but it seems to be
alright here).
