如何简化此 cmake 文件

Question

我有这个CMakeLists.txt。
从模式来看，似乎有一种更好、更干净的方法可以做到这一点。

QT5_WRAP_CPP(windowui_moc ../../include/QtDisplay/WindowUI.hpp)
QT5_WRAP_CPP(mainwindow_moc ../../include/QtDisplay/MainWindow.hpp)
QT5_WRAP_CPP(editor_moc ../../include/QtDisplay/SpiderEditor.hpp)
QT5_WRAP_CPP(output_moc ../../include/QtDisplay/OutputPane.hpp)
add_library(Display WindowUI.cpp MainWindow.cpp SpiderEditor.cpp OutputPane.cpp
                    ${windowui_moc} ${mainwindow_moc} ${editor_moc} ${output_moc})
qt5_use_modules(Display Widgets Core)

我对 cmake 中使用的约定了解不多，所以我无法查找"解决方案"的名称。

Answer 1

您是否正在寻找这样的东西：

set (Display_src
    ${PROJECT_SOURCE_DIR}/WindowUI.cpp
    ${PROJECT_SOURCE_DIR}/MainWindow.cpp
    ${PROJECT_SOURCE_DIR}/SpiderEditor.cpp
    ${PROJECT_SOURCE_DIR}/OutputPane.cpp
)
set (Display_hdr
    ${PROJECT_SOURCE_DIR}/../../include/QtDisplay/WindowUI.hpp
    ${PROJECT_SOURCE_DIR}/../../include/QtDisplay/MainWindow.hpp
    ${PROJECT_SOURCE_DIR}/../../include/QtDisplay/SpiderEditor.hpp
    ${PROJECT_SOURCE_DIR}/../../include/QtDisplay/OutputPane.hpp
)
qt5_wrap_cpp (Display_hdr_moc ${Display_hdr})
add_library (Display 
    ${Display_src}
    ${Display_hdr_moc}
)
# For Qt 5.2+
target_link_libraries (Display Qt5::Widgets)    
# For Qt 5.1.
# qt5_use_modules(Display Widgets Core)

你可以像这样使用 CMake 的 automoc 功能：

set(CMAKE_AUTOMOC ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
add_library(Display MainWindow.cpp SpiderEditor.cpp OutputPane.cpp)
qt5_use_modules(Display Widgets Core)
