Unable to build fltk-flow

[caesay]

Hi there, thanks for your effort porting important fltk libraries to Rust!

I'm having a problem compiling flow at the moment.

Environment:

Windows x64 1.78.0

Dependencies:

[dependencies]
fltk = "1.4"
fltk-theme = "0.7"
fltk-flow = "0.2"

Error:

error: failed to run custom build command for fltk-flow v0.2.3
fatal error C1083: Cannot open include file: 'cfltk/cfl_macros.h': No such file or directory

Full Log:

Hi

Thank you for your kind words and for the report.
I tried building and it failed as well, although not the same error message.
The bindings needed updating and the build script now specifies the msvc flag /std:c++17 to build fltk-flow.
I've published version 0.2.4.

The same project dependencies now work for me. Can you try cargo clean && cargo update, then try building again?
