C++ Compiling/Including all files . cpp from the subdirectories of the /src folder

Question

I use Visual Studio Code + Mingw.

My project is the https://github.com/KaueAlves/Grimorie-Tabuleiro

As some IDES link between classes automatically, when using VSCODE I came across the need to pass the compilation parameters.

How do I read all the files .cpp of all directories in /src and then generate the output .exe?

My markfile is currently like this, Focusing it works only on the levels I add to FOLDERS :

#LIBARIES := 
#INCLUDES :=
FOLDERS  := src/*.cpp src/*/*.cpp
FILES    := main.cpp
all:
    g++ -g  -std=c++17  -Wall   $(INCLUDES) $(FOLDERS)  $(FILES)    -o  main

You can use wildcards for this. It would look something like this (not tested):

src = $(wildcard *.cpp) \
      $(wildcard src/*.cpp) \
      $(wildcard src/pecas/*.cpp)
obj = $(src:.cpp=.o)

CXXFLAGS= -O2 -std=c++17 -Wall

game: $(obj) 
    $(CXX) $(CXXFLAGS) -o $@ $^

.PHONY: clean
clean: 
    rm -f $(obj) game

Furthermore, I strongly recommend that you start using Cmake for your projects. The syntax is more intuitive than GNU Make.
