Nix C++ compiler, CMake, Boost skeleton --- stable ABI

default.nix

# Nix skeleton for compiler, cmake, boost.
# Dependencies (boost and others you specify) are getting built with selectec compiler (for ABI compatibility).
# Examples:
#   nix-shell --argstr compiler gcc5 --run 'mkdir build && cd build && cmake .. && cmake --build .'
#   nix-shell --argstr compiler gcc6 --run 'mkdir build && cd build && cmake .. && cmake --build .'
#   nix-shell --argstr compiler clang_38 --run 'mkdir build && cd build && cmake .. && cmake --build .'
