Sources from subdirectories in Makefile

Question

I have a C++ library built using a Makefile. Until recently, all the sources were in a single directory, and the Makefile did something like this

SOURCES = $(w

Answer 1

If you don't want to use recursive makefiles, this might give you some ideas:

subdirs := $(wildcard */)
sources := $(wildcard $(addsuffix *.cpp,$(subdirs)))
objects := $(patsubst %.cpp,%.o,$(sources))

$(objects) : %.o : %.cpp
