[CMake] -pipe, -g and -fPIC on WIN32

[Salvatore Iovene]

Hi list,
I'm doing the following:

CHECK_CXX_COMPILER_FLAG("-fPIC" HAVE_FPIC_FLAG)

IF(HAVE_FPIC_FLAG)
  SET(${CMAKE_CXX_FLAGS} "${CMAKE_CXX_FLAGS} -fPIC")
ENDIF(HAVE_FPIC_FLAG)

And the same with -pipe and -g.

This works fine in Linux, but when trying on WIN32 with Visual Studio
command line prompt, I get that the check for the flag succedes, but
then the compiler options are actually -pipe -g -fPIC and the compiler
issues a warning about ignoring those unknown options.

What is the right way of doing this?
Thanks!
