Hello I'm an absolute begginer to programming and I'm following Stroustrap's book. I'm trying to download FLTK to make it work with C++. When I download FLTK and open fltk.snl a message appears telling me that one or more projects in the solution were not loaded correctly. When I close the message I see that none of the projects loaded correctly and solutions window for every project says that vcxproj" could not be found.
What can I do??
