Description

We currently maintain two build systems in parallel with autotools still being used by the larger part of contributors and cmake catching up in terms of coverage and features.

 

This has lead to situations where certain features were added only to the autotools build while updating the cmake build was either implicitly (without creating a ticket) deferred or forgotten. Identifying such missing coverage makes it harder to gauge where the two build systems stand in terms of feature parity and how much work is left before autotools can be retired.

We should update the cmake build setup to explicitly check whether any sources files (headers and sources) unknown to it exist in the tree. Until full parity is reached we would likely need to maintain a whitelist of files known to be missing in the cmake build (this whitelist would at the same time serve as a TODO list). The LLVM project uses the following function to perform closely related work, https://github.com/llvm-mirror/llvm/blob/master/cmake/modules/LLVMProcessSources.cmake#L70-L111.
