我试图在OS X上设置一个cmake项目。我几乎已经编译好了但是我在使Qt5工作时遇到了一些麻烦。
当我尝试编译时,我得到:
fatal error: 'QtCore/QDir' file not found
fatal error: 'QtCore/QDate' file not found
当我查看我的代码时,IDE会将QtCore和QtWidgets都以红色突出显示,表示找不到它们。
你们中有谁知道我错过了什么?
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)

答案 0 :(得分:1)
您的foreach
loops被窃听。
在这两种情况下,您都要覆盖要使用第一个元素循环的值列表。
他们应该阅读以下模式:
foreach(_loop_var ${list_of_values})
# do stuff with ${_loop_var}
endforeach(_loop_var)
我确定您遇到的问题仅仅是CMake没有搜索您想要搜索的所有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)无用。如果您不想向CMake提供大量命令行参数来指定具体位置,read about toolchain files。
如果此CMakeLists文件是来自某个地方的示例模板,我建议不要将该源用于CMake相关建议。
