-While i already provided the gdb/gdbserver-15 statically compiled binaries handed out to you, some people might want to compile it to a different architecture, or compile a newer version of gdb in the future :).

-When specifying the compilation dir throughout the compilation process (specified as <COMPILATION_DIR_PATH> in this file), DO NOT use relative pathing, or bash characters such as `~`. They will not get parsed correctly! Instead, use absolute paths only.
