[Flac] Flac in Sox

[TJF]

Hi,

I didn't get any answer for my problem at sox mailing list. May be 
someone on this list has an idea...?

I want to compile libsox.lib with Flac-handler. So I first compiled 
"libFLAC_static.lib" without problems. Then I changed "CMakeLists.txt":

I added this line:
set(CMAKE_REQUIRED_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} libFLAC_static.lib)
and now Have_Flac is found.

But there is still a problem with this line:
optional(HAVE_FLAC FLAC/all.h FLAC FLAC__stream_encoder_new flac)
because "FLAC__stream_encoder_new" is not found (cmake)!

Should this be in an other library or...?

Thanks a lot!
Regards
Thomas
