Link error in converting qmake to cmake

I have a simple project in Qt Creator (based on Qt 5.8) using RTI DDS Libraries. My project is successfully built and linked in Qt by qmake as the tool build.

Now I want to build my project with cmake build tool. So I write the below CmakeLists.txt. But I get the link error to RTI libraries. I have brought both qmake and cmake file. Please tell me what I am doing wrong;

qmake (.pro file):

QT += core
QT -= gui

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

TARGET = untitled
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

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

Link errors:

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

Thanks in advance for your help. Reza

Solution

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

These symbols are defined in -ldl. Simply add ${CMAKE_DL_LIBS} to target_link_libraries().
