CMake build link time error

Hello @troelsfr and @swernli,

I tried to build QAT with CMake and got the following link errors:

Could you help me where I went wrong in the setup ?

Hi @hamidelmaazouz, what kind of build environment are you using? It may affect what binaries are available on the system to link against.

As an example of a build environment, check out the development container configured in the repository, where the Dockerfile specifies what dependencies get installed on Ubuntu 22.04: https://github.com/qir-alliance/qat/blob/main/.devcontainer/Dockerfile
