Unable to build client

I am struggling to build the client.
Issues:

• Need CMake 3.17, not CMake 3.14+
• Had to manually disable SDL2 from CMake (maybe there was a command for this?)
• CMake wanted to build example that does not exist (CMake indicated it should have been in examples, but I could not find it.)
• CMake errors out during linking something about CMake -E (I just stopped at this point)

I am not a CMake guru, I disabled OpenSSL in my CMake 3.21 build from source. I changed it to use direct-draw-on-buffer, but it then complained about image.bmp. I tried commenting that out. This is on Linux.

I am trying to test my library against this code base. I found two bugs in server.
Issues:

• Possible race condition using mFrameCount to switch buffers inside thread (rare)
• Pixels per panel is not computed correctly: width * width (easy fix)

Start with the CMake configuration and example references, then reproduce the Linux build using the reported CMake versions and options, including SDL2, OpenSSL, and direct-draw-on-buffer. After the build path is understood, inspect the server’s mFrameCount buffer switching and pixels-per-panel calculation. Done means the client builds successfully and the reported server problems are confirmed and resolved.
