[CMake] How about GNU Automatic Variables

[Zhang Xianyi]

Hi,

I want to use cmake for a library which supports different floating point
precision.

In Makefile, I used $(*F)  to generate the different function name.

Could I use $(*F) in cmake?


==================

test.c

===============

#ifdef DOUBLE


#define TYPE double


#else


#define TYPE float


#endif



void CNAME(TYPE * a)

{

  a[0]=1.0;

}


===========

Makefile

================

OBJS=test_single.o test_double.o

all:$(OBJS)

      ar -rua libtest.a $(OBJS)

test_single.o : test.c

        $(CC) -DCNAME=$(*F) -UDOUBLE -c $< -o $(@F)

test_double.o : test.c

        $(CC) -DCNAME=$(*F) -DDOUBLE -c $< -o $(@F)


============

Thank you

Xianyi
