HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.

ntl-11.4.3 installs /usr/local/include/NTL/version.h, not /usr/local/include/version.h.

Previous versions found NTL w/out problems.

@yurivict The file "cmake/FindNTL.cmake" has not changed since HElib v1.0.2 of 9 months ago. The search path for NTL version file should resolve to "/usr/local/include/NTL/version.h" .

Can you provide the exact instruction to reproduce the problem you experienced, pls? Thanks

I can't reproduce this now with 2.1.0
