I’m using the following find module in my project:

```auto
find_path(LIBVTERM_INCLUDE_DIR vterm.h)
find_library(LIBVTERM_LIBRARY vterm)

find_package_handle_standard_args(libvterm
  REQUIRED_VARS LIBVTERM_INCLUDE_DIR LIBVTERM_LIBRARY)

add_library(libvterm INTERFACE)
target_include_directories(libvterm SYSTEM BEFORE INTERFACE INTERFACE ${LIBVTERM_INCLUDE_DIR})
target_link_libraries(libvterm INTERFACE ${LIBVTERM_LIBRARY})

```

I then realized that this works just fine even if I don’t include `FindPackageHandleStandardArgs`. This begs the question: is including FindPackageHandleStandardArgs ever necessary?

Yes, it is necessary to include the module before using it.

In your case, by chance, `FindPackageHandleStandardArgs` was already included by some other module. But to ensure the correct behavior of your module in all situations, including `FindPackageHandleStandardArgs` is required.

Wow, so find modules does not have their own scope. I see. OK, thanks for the help.

`CMake` commands are **always** global.

And modules don’t have, by default, a scope for variables or policies, but it is easy to manage one with the commands [block()](https://cmake.org/cmake/help/latest/command/block.html) and [endblock()](https://cmake.org/cmake/help/latest/command/endblock.html).
