我在 Ubuntu 16.04 上安装了 libfreenect。然后当我在 Qt 中添加它的库时，出现以下错误。

我尝试添加 libusb-1.0。我在终端输入了这个：

pkg-config libusb-1.0 --libs --cflags -I/usr/include/libusb-1.0 -lusb-1.0

但同样的错误再次发生。我该如何解决？

我认为错误信息是不言自明的。您没有安装libusb-1.0.0开发包（即libusb-1.0.0-dev）。

首先检查您是否libfreenect-dev安装了软件包（请注意，这是一个与 不同的软件包libfreenect）。如果已安装，则很可能您的libusb-1.0.0-dev软件包已损坏，您应该重新安装它。如果没有安装，你应该安装libfreenect-dev包。

安装libusb-1.0.0-dev：

sudo apt-get install libusb-1.0.0-dev

安装libfreenect-dev：

sudo apt-get install libfreenect-dev

请注意，libusb-1.0.0-dev和libusb-1.0.0是两个不同的包，也是libfreenect和libfreenect-dev。
