steps to reproduce:
1.

sudo apt-get install build-essential cmake git pkg-config libboost-dev libboost-date-time-dev \
       libboost-system-dev libboost-filesystem-dev libboost-thread-dev libboost-chrono-dev \
       libboost-serialization-dev liblog4cpp5-dev libuhd-dev gnuradio-dev gr-osmosdr \
       libblas-dev liblapack-dev libarmadillo-dev libgflags-dev libgoogle-glog-dev \
       libgnutls-openssl-dev libpcap-dev libmatio-dev libpugixml-dev libgtest-dev \
       libprotobuf-dev protobuf-compiler python3-mako

then
sudo ldconfig
then

cd gnss-sdr
git checkout next
mkdir build
cd build
cmake -DENABLE_CUDA=ON ..
make -j8

Hi,

Based on the discussion here, please try it with make rather than make -j8
Thanks.
