我正在构建一个多平台库,最近对源文件进行了更改。
基本上,我现在得到了:
\sources
|----\common
|---- tcp_socket.cpp
|----\windows
|---- tcp_socket.cpp
|----\unix
|---- tcp_socket.cpp
虽然它在mac / linux和一些VC ++版本上编译得很好,但是我的库中的一些用户遇到了愚蠢的MSVC错误:
MSB8027 Two or more files with the name of tcp_socket.cpp will produce outputs to the same location. This can lead to an incorrect build result. The files involved are ..\Classes\socket\tacopie\network\common\tcp_socket.cpp, ..\Classes\socket\tacopie\network\unix\tcp_socket.cpp, ..\Classes\socket\tacopie\network\windows\tcp_socket.cpp. test C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppBuild.targets 936
我一遍又一遍地看到的解决方案就像这里报道的那样:VisualStudio project with multiple sourcefiles of the same name? 基本上,将VC ++中项目属性的输出文件配置的Object Filename属性从$(IntDir)更改为$(IntDir)%(RelativeDir)。
这听起来像是一个有效的解决方案,但我想直接从CMakelist设置它,否则,我的图书馆用户必须自己做这个技巧。
有没有办法用CMake实现这个目标?
