將qmake轉換爲cmake時的鏈接錯誤

我在使用RTI DDS庫的Qt Creator（基於Qt 5.8）中有一個簡單的項目。我的項目是，成功構建並在Qt中通過qmake鏈接作爲工具構建。將qmake轉換爲cmake時的鏈接錯誤

現在我想用cmake構建工具來構建我的項目。所以我寫了下面的CmakeLists.txt。但是我收到RTI庫的鏈接錯誤。我帶來了qmake和cmake文件。請告訴我我做錯了什麼;

QMAKE（.pro文件）：

QT += core 
QT -= gui 

DEFINES += "_GLIBCXX_USE_CXX11_ABI=0" 
QMAKE_CXXFLAGS+=-std=c++11 

TARGET = untitled 
CONFIG += console 
CONFIG -= app_bundle 

TEMPLATE = app 

SOURCES += main.cpp \ 
    datawriter.cpp \

    ../../../Repositories/tests/r.karimi/Publisher/data/IDLs/myIDL/myIDLImplPlugin.cxx 

HEADERS += \ 
    datawriter.h \ 
    ../../../Repositories/tests/r.karimi/Publisher/data/IDLs/myIDL/myIDL.hpp \

QMAKE_CXXFLAGS += -DRTI_UNIX 
QMAKE_CXXFLAGS += -DRTI_LINUX 
QMAKE_CXXFLAGS += -DRTI_64BIT 

unix:LIBS += -L$$(NDDSHOME)/lib/x64Linux3gcc4.8.2 -lnddscd -lnddscored -lnddscpp2d -lrtidlcppd -lrtirsinfrastructured 
INCLUDEPATH += .. \ 
       $$(NDDSHOME)/include/ndds/hpp \ 
       $$(NDDSHOME)/include \

在此先感謝您的幫助。禮

可能重複[需要鏈接cmake項目到dl庫]（https://stackoverflow.com/questions/33678965/need-to-link-cmake-project-to-dl-library） – Tsyvarev

.../libnddscored.so: undefined reference to `dlopen' 
.../libnddscored.so: undefined reference to `dlclose' 
.../libnddscored.so: undefined reference to `dlerror' 
.../libnddscored.so: undefined reference to `dlsym'

這些符號在-ldl定義。只需將${CMAKE_DL_LIBS}添加到target_link_libraries()即可。
