[Gong Zhang]

Hi List,
I'm trying to check the example howto_square_ff with gr_modtool.I work
with ubuntu10.04,gnuradio 3.6.1 and cmake2.8.1.When I excute 'cmake ../'
in /gnuradio3.6.1/build.I got the following:
-- Configuring gr-wxgui support...
-- Dependency ENABLE_GR_CORE = ON
-- Dependency ENABLE_PYTHON = ON
-- Dependency NUMPY_FOUND = TRUE
-- Dependency WX_FOUND = TRUE
-- Enabling gr-wxgui support.
-- Override with -DENABLE_GR_WXGUI=ON/OFF
