CocoaPods 1.5.0 support for static libraries

[sasojadrovski]

Hey @HamzaGhazouani,

I have updated CocoaPods to v.1.5.0 and tried building the dependencies as static libraries. The pod update command succeeded, however, when building the application, I get the following errors for HGPlaceholders:

Unable to run command 'StripNIB PlaceholderCollectionViewCell.nib' - this target might include its own product.
Unable to run command 'StripNIB PlaceholderCollectionViewCell~iphone.nib' - this target might include its own product.
Unable to run command 'StripNIB PlaceholderCollectionViewCell~ipad.nib' - this target might include its own product.
Unable to run command 'StripNIB PlaceholderTableViewCell.nib' - this target might include its own product.
Unable to run command 'StripNIB PlaceholderTableViewCell~iphone.nib' - this target might include its own product.
Unable to run command 'StripNIB PlaceholderTableViewCell~ipad.nib' - this target might include its own product.

Could you please take a look?

Cheers,
Sasho
