<p>I'd like to skip the tests and create a (default) Makefile.</p>

Of course you can write a makefile by hand. A quick googling shows LOTS of tutorials.
This one
looks promising.
For the cliffs notes version, the example boils down this:
```
```
CC=g++
CFLAGS=-c -Wall
LDFLAGS=
SOURCES=main.cpp hello.cpp
OBJECTS=$(SOURCES:.cpp=.o)
EXECUTABLE=hello

all: $(SOURCES) $(EXECUTABLE)

$(EXECUTABLE): $(OBJECTS) 
    $(CC) $(LDFLAGS) $(OBJECTS) -o $@

.cpp.o:
    $(CC) $(CFLAGS) $< -o $@
```
```
