如何设置路径环境变量使用CMake和Visual Studio运行测试 [英] How to Set Path Environment Variable using CMake and Visual Studio to Run Test

问题描述

我使用CMake生成Visual Studio项目文件。我想在设置PATH环境变量后运行测试可执行文件，以便能够加载所需的dll。我根据 http：//www.mail-archive .com / cmake @ cmake.org / msg21493.html 但它不工作。

您是否为此目的使用了Visual Studio的CMake？请分享您的经验。

此外，我发现没有简单的方法来调试我的CMake脚本，例如，看看它分配给PATH变量的值。使用 CMAKE_VERBOSE_MAKEFILE 设置CMake详细信息不起作用。我怎么去自己调试它？

解决方案

要在Visual Studio中从CMake设置自定义项目设置，您可以使用XML文件作为模板，可以从CMake作为 .user 文件工作。

在我的工作中，我们使用它来设置自定义调试参数。

检查包含生成的 .vcproj 文件的目录中 .user 文件中的用户设置。以下是我们使用的示例 UserTemplate.vcproj 文件的片段。

 <？xml version =1.0encoding =Windows-1252？> 
< VisualStudioUserFile 
 ProjectType =Visual C ++
 Version =9.00
 ShowAllFiles =false
> 
< Configurations> 
< Configuration 
 Name =Debug | @ USERFILE_PLATFORM @
> 
< DebugSettings 
 Command =@ USERFILE_COMMAND_DEBUG @
 WorkingDirectory =@ USERFILE_WORKING_DIRECTORY_DEBUG @
 CommandArguments =@ USERFILE_COMMAND_ARGUMENTS_DEBUG @
 Attach =false
 DebuggerType =3
 Remote =1
 RemoteMachine =@ USERFILE_REMOTE_MACHINE_DEBUG @
<！ - 更多设置已针对代码段移除 - > 
 /> 
< / Configuration> 
<！ - 其余配置 - >这样，你可以从CMake注入任何所需的变量到 .user  
文件。 
在CMake中，您可以设置适当的CMake变量（如果需要，可在模板文件中添加更多）。 
 ＃查找用户和系统名称
 SET（SYSTEM_NAME $ ENV {USERDOMAIN} CACHE STRING SystemName）
 SET（USER_NAME $ ENV {USERNAME} CACHE STRING UserName）
 
＃配置模板文件
 SET（USER_FILE $ {_ projectName} .vcproj 。$ {SYSTEM_NAME}。$ {USER_NAME} .user）
 SET（OUTPUT_PATH $ {CMAKE_CURRENT_BINARY_DIR} / $ {USER_FILE}）
 CONFIGURE_FILE（UserTemplate.user $ {USER_FILE} @ONLY）
  
 
I am using CMake to generate Visual Studio project files. I want to run the test executable after setting the PATH environment variable so that it is able to load the required dll. I tried as per the discussion at http://www.mail-archive.com/[e-mail]/msg21493.html but it does not work. 

Have you used CMake with Visual Studio for this purpose? Please share your experiences. 

Also, I find no easy way to debug my CMake script, for example to see what value it assigns to the PATH variable. Setting CMake verbose with CMAKE_VERBOSE_MAKEFILE does not help. How would I go about debugging it myself? 
解决方案
For setting custom  project setting in Visual Studio from CMake you can use a XML file as a template which can be configured from CMake to work as the .user file.

At my work we use this to set custom debug parameters.

Check the directory containing the generated .vcproj files for the user settings in the .user files. Here is a snippet of an example UserTemplate.vcproj file we use.
<?xml version="1.0" encoding="Windows-1252"?>
  <VisualStudioUserFile
    ProjectType="Visual C++"
    Version="9.00"
    ShowAllFiles="false"
    >
    <Configurations>
        <Configuration
            Name="Debug|@USERFILE_PLATFORM@"
            >
            <DebugSettings
                Command="@USERFILE_COMMAND_DEBUG@"
                WorkingDirectory="@USERFILE_WORKING_DIRECTORY_DEBUG@"
                CommandArguments="@USERFILE_COMMAND_ARGUMENTS_DEBUG@"
                Attach="false"
                DebuggerType="3"
                Remote="1"
                RemoteMachine="@USERFILE_REMOTE_MACHINE_DEBUG@"
                            <!-- More settings removed for snippet -->
            />
        </Configuration>
            <!-- Rest of Configurations -->
This way you can inject any needed variables from CMake into the .user file.
In CMake you can set the appropiate CMake variables (and add more in the template file if you need them). Next you can do something like this to configure the file.
# Find user and system name
SET(SYSTEM_NAME $ENV{USERDOMAIN} CACHE STRING SystemName)
SET(USER_NAME $ENV{USERNAME} CACHE STRING UserName)

# Configure the template file
SET(USER_FILE ${_projectName}.vcproj.${SYSTEM_NAME}.${USER_NAME}.user)
SET(OUTPUT_PATH ${CMAKE_CURRENT_BINARY_DIR}/${USER_FILE})
CONFIGURE_FILE(UserTemplate.user ${USER_FILE} @ONLY)
