KD应用不建，未定义全球化志愿服务青年到Solid库

Question

我试图建立一些KDE软件我在KDevelop的写作，但我得到这些错误：

CMakeFiles/kquickformat.dir/deviceinfo.o: In function `QList<Solid::Device>::node_destruct(QList<Solid::Device>::Node*, QList<Solid::Device>::Node*)': 
/usr/include/QtCore/qlist.h:418: undefined reference to `Solid::Device::~Device()' 
CMakeFiles/kquickformat.dir/deviceinfo.o: In function `DeviceInfo': 
/home/kemra102/projects/KDE/kquickformat/src/deviceinfo.cpp:5: undefined reference to `Solid::DeviceNotifier::instance()' 
/home/kemra102/projects/KDE/kquickformat/src/deviceinfo.cpp:7: undefined reference to `Solid::Device::listFromType(Solid::DeviceInterface::Type const&, QString const&)' 
CMakeFiles/kquickformat.dir/deviceinfo.o: In function `DeviceNotifier': 
/usr/include/KDE/Solid/../../solid/devicenotifier.h:42: undefined reference to `vtable for Solid::DeviceNotifier' 
CMakeFiles/kquickformat.dir/deviceinfo.o: In function `~DeviceNotifier': 
/usr/include/KDE/Solid/../../solid/devicenotifier.h:42: undefined reference to `vtable for Solid::DeviceNotifier' 

相关的代码如下：

#include "deviceinfo.h" 

DeviceInfo::DeviceInfo(Solid::DeviceNotifier *parent) 
{ 
    Solid::DeviceNotifier *notifier = Solid::DeviceNotifier::instance(); 

    QList<Solid::Device> list = Solid::Device::listFromType(Solid::DeviceInterface::StorageDrive, QString()); 
} 

和

#ifndef DEVICEINFO_H 
#define DEVICEINFO_H 

#include <QList> 
#include <QString> 
#include <Solid/Device> 
#include <Solid/DeviceNotifier> 
#include <Solid/StorageDrive> 

class DeviceInfo : public Solid::DeviceNotifier 
{ 
    public: 


    private: 
    DeviceInfo(Solid::DeviceNotifier *parent=0); 
    Solid::DeviceNotifier* notifier; 
    QList<Solid::Device> list; 
}; 

#endif 

我肯定已经安装了库，可以看到他们我的文件系统上，所以我不能理解Kdevelop为什么拒绝构建它。

您是否告诉CMake链接这些库？我相信你可以使用“$ {SOLID_LIBS}”var，如下所示：

target_link_libraries(... ${SOLID_LIBS} ...)
