我正在尝试为我的arm64 ubuntu16.04开发板构建libuvc,并且在安装libjpeg-dev
之后遇到此错误:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
JPEG_INCLUDE_DIR
used as include directory in directory /home/nvidia/dev/libuvc
used as include directory in directory /home/nvidia/dev/libuvc

-- Configuring incomplete, errors occurred!
看来我必须为其设置环境变量。我不熟悉ubuntu包装,我不知道如何正确设置它。有什么想法吗?
