Azure Pipeline构建依赖C++库遇LNK1181错误求助

我有一个包含三个项目的解决方案：BaseLib、MidLib、TopLib，其中TopLib依赖BaseLib和MidLib。创建Azure Pipeline按顺序构建这些库时，TopLib构建出现错误：

##[error]LINK(0,0): Error LNK1181: cannot open input file 'BaseLib.lib'

已尝试将构建成功的库文件复制到Release目录，并配置AdditionalLibraryDirectories指向该路径，但未解决问题。当前使用的YAML配置如下：

trigger:
- azure-pipelines-second

pool:
  vmImage: 'windows-latest'

variables:
  #solution: '**/*.sln'
  solution: 'Main Project.sln'
  releaseDir: '$(System.DefaultWorkingDirectory)/Release'
  baseLibProject: 'BaseLib/BaseLib.vcxproj'
  MidLibProject: 'MidLib/MidLib.vcxproj'
  TopLibProject: 'TopLib/TopLib.vcxproj'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
#Installments
- script: choco install netfx-4.8 # .NET Framework
- script: choco install windows-sdk-10-version-1903-all # Windows SDK

- task: NuGetToolInstaller@1

- task: NuGetCommand@2
  inputs:
    command: 'restore'
    restoreSolution: '**/*.sln'
    feedsToUse: 'config'
    nugetConfigPath: 'NuGet.config'

- task: MSBuild@1
  displayName: 'Build BaseLib'
  inputs:
    solution: '$(baseLibProject)'
    platform: 'x86' # Adjust this based on your target platform
    configuration: 'Release'
    msbuildArguments: '/p:DeployOnBuild=true /p:Configuration=Release /p:Platform=x86 /p:AdditionalLibraryDirectories=$(releaseDir)'

- task: CopyFiles@2
  displayName: 'Copy BaseLib Build Output'
  inputs:
    SourceFolder: '$(System.DefaultWorkingDirectory)/BaseLib/Release'
    Contents: '**/*'
    TargetFolder: '$(releaseDir)'

- task: MSBuild@1
  displayName: 'Build MidLib'
  inputs:
    solution: '$(MidLibProject)'
    platform: 'x86' # Adjust this based on your target platform
    configuration: 'Release'
    msbuildArguments: '/p:DeployOnBuild=true /p:Configuration=Release /p:Platform=x86 /p:AdditionalLibraryDirectories=$(releaseDir)'

- task: CopyFiles@2
  displayName: 'Copy MidLib Build Output'
  inputs:
    SourceFolder: '$(System.DefaultWorkingDirectory)/MidLib/Release'
    Contents: '**/*'
    TargetFolder: '$(releaseDir)'

- task: MSBuild@1
  displayName: 'TopLib'
  inputs:
    solution: '$(TopLibProject)'
    platform: 'x86' # Adjust this based on your target platform
    configuration: 'Release'
    msbuildArguments: '/p:DeployOnBuild=true /p:Configuration=Release /p:Platform=x86 /p:AdditionalLibraryDirectories=$(releaseDir)'

注：忽略.NET安装和NuGet安装步骤，后续构建应用会用到。

• 输出路径错误：指定x86平台构建时，VC++项目的默认输出路径不是项目目录/Release，而是项目目录/x86/Release或项目目录/bin/x86/Release，导致CopyFiles任务找不到要复制的库文件。
• 冗余配置：构建BaseLib时不需要指定AdditionalLibraryDirectories，因为它本身无外部依赖；MidLib依赖BaseLib，但之前的配置未正确指向BaseLib的实际输出路径。

trigger:
- azure-pipelines-second

pool:
  vmImage: 'windows-latest'

variables:
  solution: 'Main Project.sln'
  releaseDir: '$(System.DefaultWorkingDirectory)/Release'
  baseLibProject: 'BaseLib/BaseLib.vcxproj'
  midLibProject: 'MidLib/MidLib.vcxproj'
  topLibProject: 'TopLib/TopLib.vcxproj'
  buildConfiguration: 'Release'
  buildPlatform: 'x86'

steps:
# Installments (保留原步骤，忽略提示)
- script: choco install netfx-4.8 # .NET Framework
- script: choco install windows-sdk-10-version-1903-all # Windows SDK

- task: NuGetToolInstaller@1

- task: NuGetCommand@2
  inputs:
    command: 'restore'
    restoreSolution: '**/*.sln'
    feedsToUse: 'config'
    nugetConfigPath: 'NuGet.config'

# 构建BaseLib，直接输出到统一目录，无需复制
- task: MSBuild@1
  displayName: 'Build BaseLib'
  inputs:
    solution: '$(baseLibProject)'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'
    msbuildArguments: '/p:OutputPath=$(releaseDir) /p:Configuration=$(buildConfiguration) /p:Platform=$(buildPlatform)'

# 构建MidLib，输出到统一目录，同时指定依赖库路径
- task: MSBuild@1
  displayName: 'Build MidLib'
  inputs:
    solution: '$(midLibProject)'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'
    msbuildArguments: '/p:OutputPath=$(releaseDir) /p:Configuration=$(buildConfiguration) /p:Platform=$(buildPlatform) /p:AdditionalLibraryDirectories=$(releaseDir)'

# 构建TopLib，依赖库已在统一目录中
- task: MSBuild@1
  displayName: 'Build TopLib'
  inputs:
    solution: '$(topLibProject)'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'
    msbuildArguments: '/p:OutputPath=$(releaseDir) /p:Configuration=$(buildConfiguration) /p:Platform=$(buildPlatform) /p:AdditionalLibraryDirectories=$(releaseDir)'

• 统一输出路径：通过/p:OutputPath=$(releaseDir)让所有项目直接输出到指定目录，省去CopyFiles步骤，避免路径匹配错误。
• 平台一致性：所有项目使用相同的buildPlatform变量，确保生成的库和引用的库平台一致，避免因平台不匹配导致链接错误。
• 按需配置依赖路径：仅在依赖其他库的项目（MidLib、TopLib）中指定AdditionalLibraryDirectories，指向统一输出目录，确保链接器能找到依赖库。
