I have been trying to build IMP from source on Conda on my mac. It mostly goes well except in one file it gets flustered by a for-range loop (see *Build output *below). If I build using the same cmd-line just with *--std=c++11*, or *std=c++14*, or *std=c++17*, it works just fine. Moreover, cmake does detect that it should work with C++11 (see *CMake output* below). Any ideas? Thanks! Barak
