Hmm, we use try-compile check to test presence of the ASF support in TagLib. I 
see a couple of possible reasons (I haven't verified plausibility of any of 
them):
 a) distcc depends on the fact that you call it with the correct name alias, 
i.e. that you should set CMAKE_CXX_COMPILER to something like 
/usr/lib/distcc/g++; even better, cmake should pick up it automatically if you 
prepend something line /usr/lib/distcc to $PATH and remove CMakeCache.txt
 b) distcc assumes that all hosts have the same system-wide headers. In that 
case it may be needed for you to install the same TagLib version on all 
building hosts
 c) our try-compile check is simply broken if you set CMAKE_CXX_COMPILER to 
something it doesn't expect.
 d) our try-compile check is broken in a way that it uses the system-wide 
TagLib even if you specified your self-compiled; this is not likely the cause 
as I think that even TagLib 1.7 ships with ASF support by default.
