Subject: Re: [Kicad-developers] New Build Dependencies: Lemon + GTK3
To: <Ian.S.McInerney@xxxxxxxx>


Ah! No "lemon.exe", but a "lemon.lib". After a bit of digging I found that
the "lemon" package in vcpkg actually installs "lib-lemon", which is
something else (see https://github.com/Microsoft/vcpkg/pull/3779).

However, I managed to get it working by installing lemon in MSYS2/MINGW64
(pacman -S lemon) and then telling cmake the location of lemon.exe by
adding the variable "LEMON=C:\msys64\usr\bin" to the cMakeSettings.json (as
per your suggestion). That seemed to work: I'm not getting the cmake error
anymore. I'll see if it finishes compiling tomorrow.

Thanks for your help!
