I am facing error with the include directories in my cmake. I tried all the scopes possible but still get this error. The GTSAM library is in shared folder “/usr/local/include” but still I am facing error.

```auto
CMake Error at autorally/autorally_core/src/StateEstimator/CMakeLists.txt:18 (target_include_directories):
  Cannot specify include directories for target "SYSTEM" which is not built
  by this project.

```

CMakeList.txt (Line1 18 target\_include\_directories)

```auto
# SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "/usr/include/boost")
# SET(CMAKE_LIBRARY_PATH $(CMAKE_LIBRARY_PATH) "")

For target\_include\_directories() you need to specify the target name as first argument but SYSTEM ist not a target name. Maybe read the documentation of this cmake command again.
