我有以下项目结构：
- CMakeLists.txt（顶层）
- 包括
- 源文件
- 例子
- CMakeLists.txt
- example.cpp
- src
- CMakeLists.txt
- source.cpp
Top level CMakeLists.txt includes both src and examples using add_subdirectory. I want to do the same with include directory. I have no problem using the header files from include. What I want is to be able to see include directory in my IDE. Currently, QtCreator doesn't show include directory if I open the top level CMake file with it.
I know that I can add dummy CMakeLists.txt but that's a bit meh. Don't want to do this for code readers sanity sake.
