Help! With setting up OpenFHE on my Linux

I am fairly new to C++ (and linux for that matter), so would greatly appreciate some advise on how I can proceed.

I have completed all steps in Installing OpenFHE on Linux - I was able to run the sample code to test “bin/examples/pke/simple-integers”

But, when I follow the instructions on Building User Applications - I get the following error on step 7.

How do I go about resolving this?

It is clear from the error message No SOURCES given to target: fhe-demo that cmake is trying to create an executable named “fhe-demo” without specifying any source files.

cmake cannot find your code file simple-integers.cpp. Perhaps you did not specify the correct name in CMakeLists.txt, you did not identify the source path with the cmake command, or there is no code file at all.

Ensure your code file name is simple-integers.cpp stored in a source path that cmake can locate.

Thanks, for being patient and pointing out my silly mistake!

Now, as I am following the instructions listed under - How To Link Your Own Project After Having OpenFHE Installed, in the README.md of this page. I am facing the following issue;

How do I go about this?

It looks like you don’t have OpenMP installed on your system.
Try installing OpenMP, it might solve the problem.
