CANN的安装就不做过多介绍了。如果想要在QT下调用ACL库，那么在.pro文件内添加：

对应的路径在你安装的cann的相对路径下也就是${HOME}/latest/

#ACL库的依赖#
# ACL 头文件路径
INCLUDEPATH += /usr/local/Ascend/ascend-toolkit/latest/include

# ACL 库路径
LIBS += -L/usr/local/Ascend/ascend-toolkit/latest/lib64  -L/var/davinci/driver/lib64

# 链接 libascendcl.so 及其主要依赖库
LIBS += -lascendcl \
        -lascend_dump\
        -lgert \
        -lge_executor \
