CMake - 找不到文件

Question

我正在尝试使用 CMake 创建我的解决方案。这是我第一次，我从简单的事情开始。

我制作了文本文件(CMakeLists.txt)并在 CMake 中使用它。我可以“配置”而没有错误，但当我尝试生成它时出现错误:

CMake Error at CMakeLists.txt:75 (ADD_EXECUTABLE):
  Cannot find source file:

    ./source/server/server.hpp

  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
  .hxx .in .txx

这是我的文件的路径:

\QTCP_Connection\source\server (contain server.cpp and server.hpp)
\QTCP_Connection\source\qtcp   (contain main.cpp)
\QTCP_Connection\source\libs   (contain singleton_holder.hpp and stdafx.hpp and stdafx.cpp and targetver.hpp)

这是我的 CMakeLists.txt:

你能告诉我我做错了什么吗？

Answer 1

这行似乎有问题:

SET(QTCP_PROJECT_DIR .)

目录.将指向正在运行的cmake进程的工作目录，而不是CMakeLists文件的目录。

相反，你应该使用类似的东西

SET(QTCP_PROJECT_DIR ${PROJECT_SOURCE_DIR})

请参阅 PROJECT_SOURCE_DIR 上的文档变量的详细信息。

请注意，您可以使用 message如果您不确定某个变量指向什么，则进行一些简单的 printf 调试:

message("PROJECT_SOURCE_DIR points to " ${PROJECT_SOURCE_DIR})
