Question

我包含一个KF5标头（#include <KXmlGui/KXMLGUIClient>），而当我悬停指令时KDevelop向我提供了有关此标头的信息时，GCC却找不到此标头和其他（很少和随机的）KF5标头。 / p>

我正在使用CMake，并且我使用api.kde.org查找（并链接到）每个标头所需的每个模块。我想不通。

有什么想法吗？

您将必须

请确保已将XmlGui作为find_package命令的组成部分。
请确保在KF5::XmlGui中为相关目标添加target_link_libraries。

如果您想知道为什么target_link_libraries影响您的包含路径，您并不孤单-但这就是它的工作方式。

GCC找不到标头，但KDevelop已对其进行了解析。怎么解决？
