FetchContent ITK gives strange error (include): include called with wrong number of arguments.

Usage

Hi,
I’m trying to use FetchContent to download ITK and build my project. But I got this string error:

CMake Error at CMakeLists.txt:18 (include):
include called with wrong number of arguments. include() only takes one
file.

Does anybody know why I am getting the include error?

Here is my CMakeLists.txt file:

cmake_minimum_required(VERSION 3.19.7 FATAL_ERROR)

project(nebula LANGUAGES CXX)

set(BUILD_TESTING OFF)
set(BUILD_EXAMPLES OFF)

include(FetchContent)
FetchContent_Declare(
  ITK
  GIT_REPOSITORY https://github.com/InsightSoftwareConsortium/ITK.git
  GIT_TAG        v5.3.0 
  FIND_PACKAGE_ARGS NAMES ITK
)
FetchContent_MakeAvailable(ITK)

find_package(ITK REQUIRED)
include(${ITK_USE_FILE})

add_executable(nebula hello_world.cpp)
target_link_libraries(nebula ${ITK_LIBRARIES})

My guess is that ITK_USE_FILE is not set. Modern ITK might not provide this variable. You can guard it with an if (ITK_USE_FILE) check.
