FindCairo
--------------
Find Cairo headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``Cairo::Cairo``
The Cairo library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``Cairo_FOUND``
true if (the requested version of) Cairo is available.
``Cairo_VERSION``
the version of Cairo.
``Cairo_LIBRARIES``
the libraries to link against to use Cairo.
``Cairo_INCLUDE_DIRS``
where to find the Cairo headers.
``Cairo_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
