Building Cocoapod library with GoogleMaps SDK

Question

I want to use GoogleMaps in My Cocoapod library.

There is GoogleMaps in cocoapod. but, you can't use dependency because it is static library. probably...

I referenced this answer.
Building a Cocoapod with Swift and dependency on Objective-C framework
And, building library was succeeded.

I have problem when using builded library in Example project.

When I built Example project, first problem is

ld: framework not found GoogleMaps for architecture arm64

And, I tried to add GoogleMaps to Example project's Podfile.
next problem is

The 'Pods-MapLibraryWrapper_Example' target has frameworks with conflicting names: GoogleMaps.

Is there a way to solve the problem? or, Is there a other way to use GoogleMaps?

Thanks.

Part of My library's podspec.

  s.platform     = :ios, '8.0'
  s.requires_arc = true

  s.source_files = 'Pod/Classes/**/*'
  s.resource_bundles = {
    'MapLibraryWrapper' => ['Pod/Assets/*.png']
  }
  s.ios.resource_bundle = { 'MapLibraryWrapper-ios' => 'Resources/*.png' }

  s.public_header_files = 'Pod/Classes/**/*.h'
  s.frameworks = "Accelerate", "AVFoundation", "CoreData", "CoreLocation", "CoreText", "Foundation", "GLKit", "ImageIO", "OpenGLES", "QuartzCore", "SystemConfigurati\
on", "GoogleMaps"
  # s.dependency 'GoogleMaps'
  s.libraries = "c++", "icucore", "z"
  s.vendored_frameworks = 'Dependencies/GoogleMaps.framework'

  s.prepare_command = './download-googlemaps.sh'
