如果路径随后更改,则cmake/errors上的相对路径

Question

我有一个VS 12解决方案与我自己的项目,这取决于一些依赖项(使用cmake生成的项目文件).我使用cmake生成了这些VS12项目,并将这些项目添加到我的解决方案中(使用相对路径).然后我不得不调整这些项目的输出目录,在我自己的项目可以找到的其他地方构建目标(所以在路径更改后再次运行cmake不能解决我的问题,因为我必须编辑所有项目然后再)).

如果现在解决方案的绝对路径发生变化,解决方案仍然可以找到项目 - 但是在构建时我从cmake收到错误,"旧路径"不存在.

重现我的问题的步骤:

1. 从这里下载cmake项目.
2. 提取到目录上 C:\cmake
3. 在名为的目录内创建 C:\cmake\build
4. 打开命令行然后转到 C:\cmake\build
5. 执行 cmake ..
6. 将C:\cmake目录重命名为C:\cmake2
7. 打开解决方案 C:\cmake2\build\CMake.sln

会出现一个包含错误的长列表(这里包括完全包含的时间太长) - 所有这些都是因为旧路径"C:\ cmake \"仍在某处使用而导致的.一个例子:

1>------ Build started: Project: ZERO_CHECK, Configuration: Debug Win32 ------
2>------ Skipped Build: Project: RUN_TESTS, Configuration: Debug Win32 ------
2>Project not selected to build for this solution configuration 
1>  Checking Build System
1>  CMake is re-running because C:/cmake/build/CMakeFiles/generate.stamp dependency file is missing.
1>CUSTOMBUILD : CMake error : The source directory "C:/cmake" does not appear to contain CMakeLists.txt.
1>  Specify --help for usage, or press the help button on the CMake GUI.
3>------ Build started: Project: cmbzip2, Configuration: Debug Win32 ------
4>------ Build started: Project: cmzlib, Configuration: Debug Win32 ------
5>------ Build started: Project: cmexpat, Configuration: Debug Win32 ------
6>------ Build started: Project: cmsys, Configuration: Debug Win32 ------
3>C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.Targets(1422,5): warning : The referenced project 'C:/cmake/build/ZERO_CHECK.vcxproj' does not exist.

我想只生成一次VS Project文件 - 如果文件夹的位置发生变化,则不会再次生成.有什么想法cmake可以如何使用相对路径？

即使这个问题被低估了,我也会为那些面临同样问题的人提供答案(根据他们的环境,我认为这可能是一个真正的问题).

我从我的解决方案中引用的所有项目文件中删除了至少以下部分:

      <LinkObjects Condition="'$(Configuration)|$(Platform)'=='RelWithDebInfo|Win32'">false</LinkObjects>
    </CustomBuild>
  </ItemGroup>

和:

<ItemGroup>
    <ProjectReference Include="C:/cmake/build/ZERO_CHECK.vcxproj">
      <Project>FE0DC35D-28F6-4786-A563-DFE14862A57F</Project>
    </ProjectReference>
</ItemGroup>

这可以防止在每次构建之前检查CMakeLists.txt的更改行为.如果项目文件中的所有其他路径都是相对的,则cmake项目现在可以在硬盘上自由移动.

此自定义生成步骤的问题是:它不显示在Visual Studios项目设置中,因此必须手动编辑普通的.vcxproj.
