Dim*_*los 11 c++ linux qt qt4 cmake
方案:
在add_executable()语句中添加资源文件
(不在add_library())
无法设置主窗口图标.
备注:
当我不使用时,AUTORCC我遇到了一些编译问题:
QtCore/qglobal.h: no such file or directory.但是,我更喜欢AUTORCC作为一种更现代的CMake方法.
如果没有AUTORCC(与提供的CMakeLists.txt不同)和Qt-4.6.2,则当前代码无效.不同的CMakeLists.txt)

我认为你需要链接qrc_resources生成的文件.
我想你知道下一个信息:
http://www.cmake.org/cmake/help/v3.0/manual/cmake-qt.7.html
在哪里可以看到下一行:
add_executable(myexe main.cpp resource_file.qrc)

我不确定这是否是新的,但我已经找到了一种向库添加资源的方法。
在我图书馆的 CMakeLists.txt 中,我有以下内容:
list (APPEND RESOURCES library.qrc)
qt5_add_resources (RCC_SOURCES ${RESOURCES})
...
add_library(library ${RCC_SOURCES} ${SOURCES})

在库中,在我的一个“主类”中(对我来说,这个类是在库中创建的第一个东西,也是最后一个被销毁的东西),我做了以下事情:
class libClass : public QMainWindow {
Q_OBJECT
public:
libClass() : QMainWindow(nullptr, 0) {
Q_INIT_RESOURCE(library);
}
~libClass() {
Q_CLEANUP_RESOURCE(library);
}
};
