Carthage build fails #2
Description
Despite the changes I've made in PR #1, Carthage builds still fail with the following type of errors:
clang: error: no such file or directory: '.../Carthage/Checkouts/SQLiteCipher.swift/Vendor/sqlcipher/sqlite3.c'
If I manually open the Xcode project and build the framework, and then copy the sqlite3.c file to the carthage checkout, the build completes (albeit with 19 warnings) and a ~ 20MB framework is generated, containing both SQLiteCipher.swift and sqllitecipher.a. It seems to me that Carthage does not properly build the target dependencies of SQLiteCipher.swift, thereby not creating the sqlite3.c file.
