FluentUI cannot be used in pod subspecs with multiple targets in a single Xcode project

Environment Information

• Platform:
  • iOS
  • macOS
• Package version(s): CocoaPods 0.2.7
• Xcode and OS versions: Xcode 12.5

Please provide a reproduction of the bug:

1. Create an Xcode project, add an additional target to the project
2. pod init, and use subspec to add dependencies to each targets, for example

target 'FluentUIBuildingIssue' do
  use_frameworks!
  pod 'MicrosoftFluentUI/Shimmer_ios', '~> 0.2.5'
  pod 'MicrosoftFluentUI/ActivityIndicator_ios', '~> 0.2.5'
end

target 'FluentUIBuildingIssueTarget2' do
  use_frameworks!
  pod 'MicrosoftFluentUI/HUD_ios', '~> 0.2.5'
end

3. pod install and try to build a target

Actual behavior:

xcodebuild: error: The project '****/FluentUIBuildingIssue/Pods/Pods.xcodeproj' does not contain a target named 'MicrosoftFluentUI-FluentUIResources-ios'.

CocoaPods created separate targets in the Pods.xcodeproj, the script in [CP-User] Optimize resource bundle does not match MicrosoftFluentUI-FluentUIResources-ios.

Expected behavior:

It should build fine.

Reproduce the issue with the two-target Podfile, run pod install, and inspect Pods/Pods.xcodeproj plus the [CP-User] Optimize resource bundle script. Done means xcodebuild builds both iOS targets without the missing MicrosoftFluentUI-FluentUIResources-ios target error.
