我有一个专门用cmake . -> make构建的应用程序，它似乎使用Qt4库（CMakeLists文件的一部分）：
include_directories("/usr/include/qt4/QtXml")
include_directories("/usr/include/qt4")
include_directories("/usr/include/qt4/Qt")
include_directories("/usr/include/qt4/QtCore")
include_directories("/usr/include/qt4/QtXml")
include_directories("/usr/include/qt4/QtGui")
include_directories("/usr/include/qt4/QtOpenGL")
ADD_DEFINITIONS(${QT_DEFINITIONS})
if(EXISTS "${ROOT}/usr/lib/x86_64-linux-gnu/libQGLViewer.so")
message(STATUS "Found qglviewer2, linking QGLViewer")
set(QGLVIEWER QGLViewer)
else()
message(STATUS "Did not find qglviewer2, linking qglviewer-qt4")
set(QGLVIEWER qglviewer2-qt4)
endif()
FIND_PACKAGE(Qt4 REQUIRED)
QT4_WRAP_CPP(onlinefusion_HEADERS_MOC onlinefusionviewer.hpp)
add_executable(onlinefusion
onlinefusionviewer_main.cpp
onlinefusionviewer.cpp
${onlinefusion_HEADERS_MOC}
)
target_link_libraries(onlinefusion
geometryfusion_mipmap_cpu geometryfusion_aos
camerautils
auxiliary
${OpenCV_LIBS}
${QGLVIEWER}
QtCore QtGui QtOpenGL
GL GLU glut GLEW
boost_thread
boost_system
)
这个程序构建正常，似乎我已经在我的Ubuntu 16.04上包含了所有必需的Qt4。然而，启动程序会导致崩溃，其中包含对Qt5的大量引用：

我尝试将上面的CMakeLists中的链接库QtCore QtGui QtOpenGL更改为系统中存在的libQtCore.so.4 libQtGui.so.4 libQtOpenGL.so.4，但它仍然会在引用libQt5Core时崩溃。
我可以做些什么来正确构建它？看起来只是finding package for Qt4无效。
