C++ 使用CMakeLists.txt设置Qt5-未找到文件错误

我正试图在OS X上建立一个cmake项目。我几乎已经完成了编译，但我在让Qt5正常工作方面遇到了一点麻烦

当我尝试编译时，我得到：

fatal error: 'QtCore/QDir' file not found
fatal error: 'QtCore/QDate' file not found

当我签出代码时，IDE中的QtCore和QTWidget都以红色突出显示，表示找不到它们

你们知道我错过了什么吗

我的CMakeLists.txt如下：

cmake_minimum_required(VERSION 3.3)
project(miniLogbook)

subdirs(sources headers lib other)

#For a basic project, you should probably only need to edit these    variables

#Base QT directory
set(QT_PATH "/Users/rwardrup/Qt")

#Build output path of your QT Creator project
set(QT_BIN "./ml_debug")

#QT Version used, e.g. Probably found in ${QT_PATH}
set(QT_VERSION "5.7")

#Libraries to link to
set(QT_LIBRARIES Qt5::Core Qt5::Widgets Qt5::Gui)

#Libraries required. Probably the same as above minus the '::'.     find_package() will be called on these

set(QT_LIBRARIES_REQUIRED Qt5Core Qt5Widgets Qt5Gui)

find_package(Boost 1.59.0 COMPONENTS filesystem)

if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS})
    add_executable(miniLogbook ${SOURCES})
    add_dependencies(${PROJECT_NAME} ${QT_GENERATED})
    target_link_libraries(${PROJECT_NAME} ${QT_LIBRARIES}     ${Boost_LIBRARIES})
endif()

你的电脑被窃听了

在这两种情况下，您都将覆盖要与第一个元素循环的值列表

他们应按照以下模式阅读：

foreach(_loop_var ${list_of_values})
  # do stuff with ${_loop_var}
endforeach(_loop_var)

我敢肯定，您面临的问题只是CMake没有搜索到您希望它搜索的所有Qt5模块的症状。您可能需要重新检查CMake缓存和日志输出

---

旁注：将系统组件的绝对路径硬编码到CMake文件中是非常糟糕的做法。这使得CMake（几乎）毫无用处。如果您不想给CMake提供大量命令行参数来指定特定位置

---

如果此CMakeLists文件是某个地方的示例模板，我建议不要将该源代码用于CMake相关建议。

什么是

子目录

？@Torbjörn:。另外，看看您是否可以围绕此示例做些什么：谢谢。修复了foreach循环。我的项目结构类似于，其中有：root |-sources | |-main.cpp | |-CMakeLists.txt |-LibProject | |-inc | |'-test.h | |-src | | |-test.cpp |'-CMakeLists.txt |'-CMakeLists.txt
