无法在基于cmake的qt项目中加载qml文件

我正在开发基于cmake的Qt项目。 Qt版本是5.7，Ubuntu 14.04。我得到的错误是：无法在基于cmake的qt项目中加载qml文件

QQmlApplicationEngine failed to load component 
qrc:/main.qml:-1 File not found

的的CMakeLists.txt是：

file(GLOB_RECURSE UI_FILES *.ui) 
file(GLOB_RECURSE CODE_FILES *.cpp *.h)

如何从项目中删除此错误？

您可以使用QDirIterator来仔细检查应用程序包含的资源。例如，在main()：

QDirIterator it(":/", QDirIterator::Subdirectories); 
while (it.hasNext()) 
    qDebug() << it.next();

不知道Qt的资源处理如何与CMake的，我会说以下行类似的罪魁祸首。

qt5_add_resources(RESOURCE_FILES ../resources/resources.qrc) 

set(SOURCES 
    assets/assets.qrc 
    icons/icons.qrc 
    qml/qml.qrc)

为什么加一个.qrc与qt5_add_resources()，而其他人都加入到SOURCES？
