Question

我有一个应用程序可以使用QT-Creator（设置＃1）进行编译和运行。

我刚刚创建了一个CMakeLists文件，这样人们就可以在不使用QT-Creator（设置＃2）的情况下编译它，只需使用cmake。

使用设置＃2进行编译是成功的。但是，当我运行应用程序时，一些路径会得到一个奇怪的值。

例如，我有代码段：

        QDir                   qdir( qApp->applicationDirPath() );
                               qdir.cdUp();
                               qdir.cdUp();
        QString         PATH = qdir.path() + "/config/" + QString( ui->myPaths_TextBox_Filename_INPUT_TXT->toPlainText() );

当我使用设置＃1运行时，PATH字符串具有有效路径。当我使用设置＃2运行时，PATH字符串有一个奇怪的路径，如：

"/home/dimitris/.local/share/Trash/config/INPUT_PATHS.txt"

指向垃圾文件夹中的内容。

这是什么原因以及可能的解决方案是什么？到目前为止，我无法在网上找到这个有效的理由。
