How can I introduce the downloaded openFHE library into my C++project?

I have completed the configuration of the environment and downloaded the openFHE library, and all examples in the openFHE project can also be run. But I hope to use openFHE functions in my C++project, how should I import this?

I imported the header file for user/local, but there is a new header file in the header file that cannot be found

Have you followed the instructions in the Building User Applications section of the OpenFHE documentation?

Also, ensure you installed OpenFHE to a directory your user has write access to by running make install after building OpenFHE. More info on how to build and install OpenFHE can be found here.

Thank you for your reply.
