Framework added in a "wrong" way

I have a project generated with XcodeGen that works fine. Now I am trying to add a proprietary AirWatchSDK. The main file is AWSDK.framework.

When I drag and drop AWSDK.framework to the project manually, it gets added and builds just fine.

But when I use XCodeGen:

dependencies:
    - framework: SDKs/AirWatch/AWSDK.framework

The generated project looks fine, the AWSDK.framework appears in the right place, also SDKs/AirWatch/ is part of the framework search path but trying to build I get

ld: warning: PIE disabled. Absolute addressing (perhaps -mdynamic-no-pic) not allowed in code signed PIE, but used in _sha1_block_data_order from SDKs/AirWatch/AWSDK.framework/AWSDK(sha1-x86_64.o). To fix this warning, don't compile with -mdynamic-no-pic or link with -Wl,-no_pie
...
ld: unexpected bindingNone in '_sha1_block_data_order' from SDKs/AirWatch/AWSDK.framework/AWSDK(sha1-x86_64.o) for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is a very strange error I could not find any reasonable info about.

I do not think something is wrong in the configuration when manually adding the framework works, just having the addition generated by XcodeGen results in this error. So it must be something in the way XcodeGen adds the framework to the project.

Start by reproducing the generated project using the shown dependencies entry and compare its framework and linker settings with a project where SDKs/AirWatch/AWSDK.framework was added manually. Inspect the generated project’s treatment of AWSDK.framework and the reported x86_64 linker failure; done means the generated project builds successfully with the proprietary framework.
