Ran into this with the new EAP for CLion Nova. When using Ladybird as
source directory, we would recursively look in Ladybird --> Lagom -->
Ladybird when exporting components. This seems to be because
ENABLE_LAGOM_LADYBIRD is set to ON by Ladybird's CMakeLists and
something about their build, when invoked from their IDE, has buggy
behavior around the SUBDIRECTORIES directory property.
