我正在将一个纯视觉工作室的项目重构到CMake中，以使它跨平台。我在CMake方面没有广泛的经验，但是这个结构在一个测试项目中工作到调试结束。它没有包含第一个头文件（attachment.h和我似乎无法识别它。我已经搜索了其他答案，但同样的问题，但没有用，任何和所有帮助表示赞赏。CMake - Attachment.h：没有这样的文件或目录

编辑：我应该提到这个工程的窗户下，这就是为什么我很困惑，并深入到堆栈交易所

而是明确说明你的CMakeLists.txt源文件，你可以使用通配符文件，让CMake的收集您的烃源文件中的文件： 'FILE（GLOB SOURCES_FILES“ * .cpp“）' '文件（GLOB HEADER_FILES”* .h“）' 'SET（ALL_SOURCES $ {SOURCES_FILES} $ {HEADER_FILES}）' –

@ vr.one这是不推荐的，因为cmake只更新如果cmake文件已更改，则在构建时间。显式文件发现在大多数大型项目中都是标准的。 Globing是一个临时性的解决方案，我这是一个长期的项目。 – BleuGamer

@ vr.one它不一定是件好事，因为它强制CMake在每个版本上运行。 – arrowd

在类Unix系统（当然，关于EXT，UFS等 “Unixy” 文件系统，是精确的）文件访问是区分大小写的。更改

#include "Attachment.h"

到

#include "attachment.h"

已经全部小写了。 – BleuGamer

@BleuGamer你的错误信息说不是。 – arrowd

我可能是个白痴。谢谢你的收获。 – BleuGamer
