[Discuss-gnuradio] compile gnuradio in cmake

[ruiy]

I am trying to compile gnuradio by cmake. I have writen the CMakeLists to compile my program. 
It can work when I don't use qtgui. But a error occur when I use qtgui.  The error is exit code 139 which showed in  the picture following. I cannot understand what happen.

CMakeLists.txt:
cmake_minimum_required(VERSION 3.9)
project(TestQtGui)

set(CMAKE_PREFIX_PATH /home/calt/Qt5.9.4/5.9.4/gcc_64)
find_package(Qt5Widgets)
find_package(Qt5Core)
find_package(Qt5Gui)

find_package(Boost "1.35" COMPONENTS filesystem system)

set(GR_REQUIRED_COMPONENTS QTGUI)
find_package(Gnuradio "3.7.2" REQUIRED)

include_directories(
        ${GNURADIO_ALL_INCLUDE_DIRS}
)

set(SOURCE_FILES main.cpp)
add_executable(TestQtGui ${SOURCE_FILES})
target_link_libraries(TestQtGui Qt5::Widgets
        Qt5::Gui
        ${Boost_LIBRARIES}
        ${GNURADIO_ALL_LIBRARIES})

main.cpp:
#include <gnuradio/top_block.h>
#include <gnuradio/qtgui/time_sink_f.h>

int main() {
    int rate = 48000;
    gr::top_block_sptr tb = gr::make_top_block("testQtGui");
    gr::qtgui::time_sink_f::sptr t_bk = gr::qtgui::time_sink_f::make(1024, rate, "", 1);
}

errors:
home/calt/workspace/TestQtGui/cmake-build-debug/TestQtGui
Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

I can't understand what cause the exit code 139. Any wrong with my cmakelists.txt? 

I will appreciate it If you can solve. Thank you very much.
