Been using emulators for years - first classic or whatever it was called on OSX, then basilliskII/sheepshaver, and now mpw:

Here's the end of a Makefile, very unix-like:

  APPL = ${TYPE}${NAME}
  DATA = DATA${NAME}
  OBJS = ${NAME}.p.o
  LIBS = ../WordSum.asm.o ../LASysLib.a.o ../PasLib.o

  AFLAGS = 
  
  CC = SC
  CFLAGS = -mc68020 -mc68881 -b2 -Opt all 
  
  PC = Pascal
  PFLAGS = -mc68020 -mc68881
  
  LD = Link
  LDFLAGS = -w -t LApp -c MPWX -m MAIN -sg ${NAME}
  #    Link -w -t TEXT -c RWG1 -rt CODE -m HELPLOOP -sg HELPLOOP
  
  CFMFLAGS =
  # CFM = ${MPW:/mpw=/cfm}
