I use the target\_link\_libraries, but the vscode IDE show the error.  
Do you know what is the reason?

CMakeLists.txt

```auto
add_executable(iam ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp)
target_link_libraries(iam PRIVATE LibDataChannel::LibDataChannel)

```

main.cpp

```auto
#include <rtc/rtc.hpp>

```

Presumably the `LibDataChannel::LibDataChannel` is expected to provide the `rtc/rtc.hpp` header? Does its definition provide an `INTERFACE_INCLUDE_DIRECTORIES` property with a suitable value? You can ask CMake to “find” it by configuring with the `--trace-expand` flag and searching the output for the target name.
