Start with common/App.cpp at line 152 and reproduce the CMake build on Ubuntu 23.04 using the reported compiler output. Trace how NvOptimusEnablement and AmdPowerXpressRequestHighPerformance are declared or expected to be provided; done means the project compiles without these undeclared-identifier errors.
