In a CMakeLists.txt, I retrieve a Git repository with the commands:

include(FetchContent)
FetchContent_Declare(
  CMakeScripts
  GIT_REPOSITORY <Git repository>
  GIT_TAG        <hash code>
)
FetchContent_MakeAvailable(CMakeScripts)
FetchContent_GetProperties(CMakeScripts SOURCE_DIR CMakeScripts_SOURCE_DIR)

But actually, I need only one file:

include(${CMakeScripts_SOURCE_DIR}/cmake/Utils.cmake)

How to avoid retrieving the full repository?
