I am trying to add more source code files to the rasppi-64 source code directory of the RT-thread source tree. When I use the scons command to build my RT-thread application, it complains it cannot find the *.c source code files I added to the folder. I cannot find the file that lists out all the .c files for the compiler to build. What is its name and which folder does it reside in please?
The file would be similar to the contents of CMakeLists.txt in the ESP-IDF development environment.
