CMake链接accident库时头文件无法找到的问题求助

我的项目目录结构如下：

scales/
├── src/
│   ├── CMakeLists.txt
│   └── note/
│       ├── CMakeLists.txt
│       ├── accident/
│       │   ├── CMakeLists.txt
│       │   ├── include/
│       │   │   └── accident.hpp
│       │   ├── src/
│       │   │   └── accident.cpp
│       │   └── test/
│       └── note/
│           ├── CMakeLists.txt
│           ├── include/
│           │   └── music_note.hpp
│           ├── src/
│           │   └── music_note.cpp
│           └── test/
├── external/
├── test/
└── CMakeLists.txt

我实现了一个作为独立库的accident组件，它的CMake配置如下：

set (ACCIDENT accident)
file (GLOB SOURCE_FILES "${CMAKE_CURRENT_SOURCE_DIR}/src/*.cpp")
file (GLOB HEADER_FILES "${CMAKE_CURRENT_SOURCE_DIR}/include/*.hpp")
add_library (${ACCIDENT} STATIC ${HEADER_FILES} ${SOURCE_FILES})
target_include_directories (${ACCIDENT} PUBLIC "${CMAKE_CURRENT_SOURCE_DIR}/include")
add_subdirectory (test)

这个库本身运行正常。现在我想在note组件里使用这个库，希望不用写#include "../../accident/include/accident.hpp"这种相对路径，就能让IDE识别accident.hpp头文件，同时能调用accident.cpp里的代码。我尝试的note组件CMake配置如下：

set (MUSIC_NOTE music_note)
file (GLOB SOURCE_FILES "${CMAKE_CURRENT_SOURCE_DIR}/src/*.cpp")
file (GLOB HEADER_FILES "${CMAKE_CURRENT_SOURCE_DIR}/include/*.hpp")

add_library (${MUSIC_NOTE} STATIC ${HEADER_FILES} ${SOURCE_FILES})
target_include_directories (${MUSIC_NOTE}
    PUBLIC "${CMAKE_CURRENT_SOURCE_DIR}/include"
    PUBLIC "${CMAKE_CURRENT_SOURCE_DIR}/../accident/include"
)
target_link_libraries (${MUSIC_NOTE} accident)
add_subdirectory (test)

但这个配置无效，找不到accident.hpp头文件，请问我哪里错了？
