If I change it to `make` everything works correctly, but I'm not sure if it's a good solution.\r\nOn my system, CMake defaults to Ninja generator because I have defined environment variable `CMAKE_GENERATOR=Ninja`. If it's not supported, it should probably be mentioned in docs.","author":{"url":"https://github.com/eaglesemanation","@type":"Person","name":"eaglesemanation"},"datePublished":"2021-12-03T19:08:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/111/python_qt_binding/issues/111"}
