Cmake генерирует неправильные пути включения ⇐ C++

[Anonymous]

При создании следующей настройки для liba и libb в зависимых проектах создаются следующие каталоги включения:
liba/include/liba и liba, а также libb/include/libb и libb
Однако правильными каталогами включения будут:
liba/include, а также libb/include
Я понятия не имею, почему он вообще генерирует корневой каталог как путь включения, который не имеет никакого смысла в первое место.
libX/include/libX будет правильным путем включения в libX, но не в зависимых проектах.
Как заставить cmake генерировать только нужные пути включения?
