An error occurred while using macro to customize the timeout time of gtest in cmake

edit

Hi,

I used the following way to customize the timeout time of gtest in cmake, but an error occurred:

if(BUILD_TESTING)
  find_package(ament_lint_auto REQUIRED)
  find_package(InferenceEngine REQUIRED)
  ament_lint_auto_find_test_dependencies()

  macro(custom_gtest target)
    ament_add_gtest(${target} ${ARGN})
    if(TARGET ${target})
      target_include_directories(${target} PUBLIC
        ${${PROJECT_NAME}_INCLUDE_DIRS}
      )
      ament_target_dependencies(${target}
      rclcpp
      InferenceEngine)
    endif()
  endmacro()

  macro(targets)
     custom_gtest(unit_environment
       "tests/unit_environment.cpp"
       TIMEOUT 300)
  endmacro()    
  call_for_each_rmw_implementation(targets)
endif()

The error log:

CMake Error at /home/intel/ros2_ws/install/ament_cmake_gtest/share/ament_cmake_gtest/cmake/ament_add_gtest_executable.cmake:50 (add_executable):

How can I slove this problem?

Thanks very much.
