Probably you need to add ${PETSC_INCLUDE} also to the UseSLEPc.o target. Anyway, your makefile does not seem to be well formed. Try the following:

CFLAGS	   = -I../MyIncludefiles -Wno-deprecated
MYLIB	   = -L../MyLibraries -lMyLibrary
MYOBJS     = main.o UseSLEPc.o UsePETSc.o 
EXE        = MyExecutableFile

all: ${EXE}

include ${SLEPC_DIR}/conf/slepc_common

${EXE}: ${MYOBJS} chkopts
	-${CLINKER} -o ${EXE} ${MYOBJS} ${MYLIB} ${SLEPC_LIB}
	${RM} ${MYOBJS}
