使用解决方案文件夹时没有CMakePredefinedTargets [英] No CMakePredefinedTargets when using solution folders

问题描述

在CMake中使用VS解决方案文件夹时，使用以下命令：

When using VS solution folders in CMake using:

set_property(GLOBAL PROPERTY USE_FOLDERS ON)
set_target_properties(MyProject PROPERTIES FOLDER "MyProjects")

我也自动启用了
CMakePredefinedTargets 文件夹：

I'm also automatically enabling a CMakePredefinedTargets folder:

是否有避免这种行为的方法？

Is there a way to avoid this behaviour?

重置 PREDEFINED_TARGETS_FOLDER 可以重命名文件夹但不能将其删除。将 FOLDER 属性设置为INSTALL等似乎也无效。

Resetting PREDEFINED_TARGETS_FOLDER can rename the folder but not remove it. Setting the FOLDER property for INSTALL, etc. does not seem to be valid either.

谢谢。

推荐答案

编辑：查看CMake代码后，我确定可以设置 PREDEFINED_TARGETS_FOLDER 到 。我已经使用CMake 3.3.2和VS2015对它进行了测试，

Edit: After looking into the CMake code I was pretty sure you could set PREDEFINED_TARGETS_FOLDER to "". I've tested it and with CMake 3.3.2 and VS2015 using

set_property(GLOBAL PROPERTY USE_FOLDERS ON)
set_property(GLOBAL PROPERTY PREDEFINED_TARGETS_FOLDER "")

预定义的目标再次位于根级别。

the predefined targets are at root level again.

而且，如果全局 USE_FOLDERS 属性，如果 ON ，则预定义的目标将被硬连线以始终分组在 PREDEFINED_TARGETS_FOLDER 文件夹。因此，设置 Folder 的属性，例如安装将无济于事。

And, yes if the global USE_FOLDERS property if ON then the predefined targets are hard-wired to always be grouped in the PREDEFINED_TARGETS_FOLDER folder. So setting the FOLDER property of e.g. INSTALL won't help.

作为参考，请参见 cmGlobalVisualStudioGenerator.cxx 对于此行为已被明显停用 ALL_BUILD 目标：

As a reference see cmGlobalVisualStudioGenerator.cxx where this behavior was explicitly deactivated for the ALL_BUILD target:

#if 0
    // Can't activate this code because we want ALL_BUILD
    // selected as the default "startup project" when first
    // opened in Visual Studio... And if it's nested in a
    // folder, then that doesn't happen.
    //
    // Organize in the "predefined targets" folder:
    //
    if (this->UseFolderProperty())
    {
        allBuild->SetProperty("FOLDER", this->GetPredefinedTargetsFolder());
    }     
#endif
