【问题描述】：

我正在为 easypaint 添加一些镜像效果。在构建项目时，我遇到了一个问题。当我在 CMake 中运行生成时（是的，我知道 QMake 会更好，但我们必须使用 CMake），它一直在 CMakeLIsts.txt 文件中给我一个错误，说它找不到我的镜像 cpp 文件之一。我已将所有代码插入到项目中的相应文件和头文件中，并将头文件和 cpp 文件添加到 CMake 列表文件中的相应位置。

CMake 中的错误： """" CMakeLists.txt:129 (add_executable) 处的 CMake 错误： 找不到源文件： 来源/效果/mirrorrighteffect.cpp

尝试过的扩展 .c .C .c++ .cc .cpp .cxx .cu .m .M .mm .h .hh .h++ .hm .hpp .hxx .in .txx

我仔细检查了所有文件都在正确的目录中，所以我不知道问题是什么。

【问题讨论】：

sources/effects/mirrorrighteffect.h 和 sources/effect/mirrorrighteffect.cpp 是文件夹 sources/effects 还是 sources/effect？我相信你有一个错字。

哦，哇。我不敢相信我错过了。我想有时只是需要另一双眼睛。谢谢你接听。

OT：我通常在每个子文件夹中创建一个 CMakeLists.txt 并附加到源变量或为每个子文件夹创建一个静态库。

【参考方案1】：

你似乎在sources/———>>>effect<<<——-/mirrorrighteffect.cpp 中有错字。

我相信一定是sources/effects/mirrorrighteffect.cpp。
