Writing scons script to handle compilation of files in many subdirectories

I've got a project which consists of many files in subdirectories. I have a simple Makefile which handles the compilation. It looks like this: 

CC = g++ -Wall -ansi -pedantic 
all:
$(CC) -O2 engine/core/*.cpp engine/objects3d/*.cpp engine/display/*.cpp engine/io  /*.cpp engine/math/*.cpp engine/messages/*.cpp  *.cpp -o project1 -lGL -lGLU -lX11 `sdl-config --cflags --libs`

clean:
@echo Cleaning up...
@rm project1
@echo Done.

However I need to migrate to SCons. I have no idea how to write a script that would automatically handle finding all the *.cpp files in subdirectories and included them in the compilation process.

This is how to do what you have in your Makefile in SCons. You should put this Python code in a file at the root of the project called SConstruct, and just simply execute scons. To clean, execute scons -c

env = Environment()
env.Append(CPPFLAGS=['-Wall', '-ansi', '-pedantic', '-O2', '-lGL', '-lGLU', '-lX11'])

# Determine compiler and linker flags for SDL
env.ParseConfig('sdl-config --cflags')
env.ParseConfig('sdl-config --libs')

# Remember that the SCons Glob() function is not recursive
env.Program(target='project1',
            source=[Glob('engine/core/*.cpp'),
                    Glob('engine/objects3d/*.cpp'),
                    Glob('engine/display/*.cpp)',
                    Glob('engine/io/*.cpp'),
                    Glob('engine/math/*.cpp'),
                    Glob('engine/messages/*.cpp'),
                    Glob('*.cpp')])

Here is a link for using SDL with SCons.

And here is info on the SCons ParseConfig() function.
