make error

[RAJensen]

Hello.
I'm tried to install gr-baz but i run in to trouble.
I've installed gnu-radio and gnuradio-dev with apt-get.
Then i've cloned gr-baz and used:
sudo cmake -DCMAKE_PREFIX_PATH=/usr/lib/cmake/gnuradio
Everything went fine, but when i use:
sudo make
i'll get this error:
[ 2%] Building CXX object lib/CMakeFiles/gnuradio-baz.dir/baz_print_char.cc.o

make[1]: *** [lib/CMakeFiles/gnuradio-baz.dir/all] Error 2

So I would really apreciat a little help.
What is it that I missed?

do cmake -DCMAKE_INSTALL_PREFIX=/usr ..
because it's searching for other subdirectories from there.
by default it starts from /usr/local/
