log output (stdout) from within make file

How do I send the output (stdout) to a log file from WITHIN the make file? I am NOT interested in a command line solution such as "make > build.log". Listed below is my generic make file. # +--------------------------------------------------------------------------+ # : Uncomment the appropriate section below (comment all others) : # +--------------------------------------------------------------------------+ # --- For TERMINAL program library files --- # LIBS := -lm # --- For RAYLIB program library files --- LIBS := -l:raylib/libraylib.a -lm # --- For NCURSES program library files --- # LIBS := -lform -lmenu -lncurses -lm # --- For SDL program library files --- # SDLALL := -lSDL2_image -lSDL2_mixer -lSDL2_net -lSDL2_ttf -lSDL2_gfx # LIBS := sdl2-config --libs --cflags $(SDLALL) -lm # ------------------------- End of user editable code ------------------------- DASH := " +--------------------------+" VERSION := " : Script: 2024.02.12 :" TARGET := " : For Raylib Makefiles :" AUTHOR := " : By: Jan W.
