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 generate 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标头中，并且已将标头和 cpp 文件添加到 CMake 列表文件中的适当位置。
CMake 中的错误： """" CMake Error at CMakeLists.txt：129 (add_executable)： 找不到源文件： 来源/效果/镜像右效果.cpp
尝试扩展 .c .C .c++ .cc .cpp .cxx .cu .m .唰�� .hpp .hxx .in .txx
我仔细检查了所有文件是否都在正确的目录中，所以我不知道问题是什么。

你似乎在sources/———>>>effect<<<——-/mirrorrighteffect.cpp中有错别字.
我相信它一定是sources/effects/mirrorrighteffect.cpp的。
