FindDawn
--------------
Find Dawn headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``Dawn::dawn``
The Dawn library, if found.
``Dawn::native``
The Dawn Native library, if found.
``Dawn::wire```
The Dawn Wire library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``Dawn_FOUND``
true if (the requested version of) Dawn is available.
``Dawn_LIBRARIES``
the libraries to link against to use Dawn.
``Dawn_INCLUDE_DIRS``
where to find the Dawn headers.
``Dawn_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
