  Well, something like this works fine, though this is a quick and dirty solution.
  
    if (CMAKE_VERSION VERSION_LESS 3.12.0)
        find_package (PythonInterp 3 REQUIRED)
        set (_py_exe ${PYTHON_EXECUTABLE})
    else ()
        find_package (Python 3.0 REQUIRED COMPONENTS Interpreter)
        set (_py_exe ${Python_EXECUTABLE})
    endif ()
    
    execute_process (COMMAND "${_py_exe}" "-c"
        "import re, cairo; print(re.compile('/__init__.py.*').sub('',cairo.__file__))"
        RESULT_VARIABLE _PY_cairo_status
        OUTPUT_VARIABLE _PY_cairo_location
        ERROR_QUIET
        OUTPUT_STRIP_TRAILING_WHITESPACE
    )
    
    if (_PY_cairo_status EQUAL 0)
        set (PY_CAIRO ${_PY_cairo_location} CACHE STRING "Location of pycairo")
    endif ()
    
    find_package_handle_standard_args (PythonCairo DEFAULT_MSG PY_CAIRO)
