I'm new to Gnuradio and python. I'm trying to write a correlation block,
somewhere in my code I use fft filter:

gr::filter::kernel::fft_filter_ccc  *d_filter;
d_filter = new gr::filter::kernel::fft_filter_ccc(1, x_vector);

I run

cmake ../

and it complies perfectly fine, but when i try
ctest -V -R
I'll get this error:

 Traceback (most recent call last):
