title: The target ... overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig
body: <p>I have incorporate <code>SpatialIite</code> into a Xcode project which uses a header file from <code>Proj.4</code>, just one header. Both are Xcode projects and have static targets.</p>
  
  <p>I'm trying to migrate from git submodule to Cocoapods. Since static targets seems to be difficult to use with Cocoapods, I just want to have the project built in the usual way. I made podspec for <code>Proj.4</code>. After writing podfile for <code>SpatialLite</code> I got the warnings:</p>
  
  <pre><code>[!] The target `SpatialiteIOS [Debug]` overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig'.
      - Use the `$(inherited)` flag, or
      - Remove the build settings from the target.
  
  [!] The target `SpatialiteIOS [Debug]` overrides the `HEADER_SEARCH_PATHS` build setting defined in `Pods/Pods.xcconfig'.
      - Use the `$(inherited)` flag, or
      - Remove the build settings from the target.
  
  [!] The target `SpatialiteIOS [Debug - Release]` overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig'.
      - Use the `$(inherited)` flag, or
      - Remove the build settings from the target.
  
  [!] The target `SpatialiteIOS [Debug - Release]` overrides the `HEADER_SEARCH_PATHS` build setting defined in `Pods/Pods.xcconfig'.

  <p>I read <a href="https://github.com/CocoaPods/CocoaPods/issues/1125">this issue</a> but I'm pretty clueless to what the warnings mean and what can I do to fix it.</p>
  
  <p>Additionally problem, when I open the workspace as well as opening SpatiaLite project alone, both are targeted to Mac OSX 64, when it is suppose to be an iOS project. My podfile does say "platform :ios".</p>
