undefined reference to `boost::iostreams::zlib::default_compression'

[R S]

I am trying Avro in C++

When I include DataFileWriter. (as follows)
    DataFileWriter<avrocurve::curve> dfw("curve.bin", curveschema);

I get the following errors (truncated):
//usr/local/lib/libavrocpp_s.a(DataFile.cc.o): In function 
`avro::DataFileWriterBase::sync()':
DataFile.cc<http://DataFile.cc>:(.text+0x31da): undefined reference to 
`boost::iostreams::zlib::default_compression'
DataFile.cc<http://DataFile.cc>:(.text+0x31f3): undefined reference to 
`boost::iostreams::zlib::deflated'
DataFile.cc<http://DataFile.cc>:(.text+0x320c): undefined reference to 
`boost::iostreams::zlib::default_strategy'
DataFile.cc<http://DataFile.cc>:(.text+0x3220): undefined reference to 
`boost::iostreams::detail::zlib_base::zlib_base()'
DataFile.cc<http://DataFile.cc>:(.text+0x323d): undefined reference to 
`boost::iostreams::detail::zlib_base::do_init(boost::iostreams::zlib_params 
const&, bool, void* (*)(void*, unsigned int, unsigned int), void (*)(void*, 
void*), void*)'

Boost was built after I build zlib

zlib.a is in /usr/local/lib (Ubuntu 18)
libboost_iostreams.a (and other boost ".a" libraries) are also in /usr/local/lib

I know my CMake will pick this up as my ld.so.conf is configured for 
/usr/local/lib

There. is almost no known replies to this on Stackoverflow

I have wasted over three days in this and am on the verge to switching back to 
Protobuf's

Any help would be much appreciated as I would hate to abandon avro
