#
# Using gcc: gcc 4.8 don't support C++14 and make_unique. You may want to update at least to 4.9.
# gcc 5.3 and 5.4 include filesytem, but you need to add the link flag: -lstdc++fs
#
# In Windows, with CLion Allways check in File/Settings.../toolchains
# You could install MinGW-w64 from the TDM-GCC Compiler Suite for Windows which will update you to gcc 5.1.
# It is posible to follow https://computingabdn.com/softech/mingw-howto-install-gcc-for-windows/
# and install MinGW with gcc 7.1 with has STD_THREADS and fs, from: https://sourceforge.net/projects/mingw-w64/files/
#
# see at end of: https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dynamic_or_shared.html
