QAT out-of-tree driver does not include header files in build output

As of the latest version of the QAT out-of-tree driver for Hardware Version 2.0, the build output does not include any of the header files. Like the in-tree version of qatlib, I was expecting the build output to have an `include/` directory with the header files. This means to use the out-of-tree qatlib we have to manually include header files from the source tree.

Hi,

You shouldn't mix out-of-tree and in-tree files.

The header files for the out-of-tree driver are available within the directory ../quickassist/include/. You can also consult the sample applications that illustrate proper usage.

See more details in the Intel® QuickAssist Technology (Intel® QAT) Getting Started Guide for Linux* for Hardware Version 2.0

Regards,

Diego V.
