I successfully build and run the first FLTK example from Programming Principles and Practice with the commands: 

cmake ..

make 

make install

However, before using "make install"  the FL folder did not have a file named "abi-version.h" which is required by some of the files from the book's graphical library.

I understand that "make install" moves the FL folder from the download location to the /usr/local/include and the static libraries (.a files) to /usr/local/lib ... 

So I wonder why I don't have the "abi-version.h" file when only building FLTK and not installing it. 

I downloaded FLTK 1.4 from the site and from Git and the abi file is still missing.

Or maybe I did something else wrong?

Thanks for taking the time!
