Thanks for the great app.
The first graphical toolkit for Linux that makes sense, is well though out, and intuitive to use. Well done.
It's impossible to build it using a package manager. I use Arch Linux and this package is impossible to build using the pacman package manager. The Makefile.PL looks more like a c style makefile. It's in perl code but doesn't resemble a perl Makefile.PL.
KeyKey 'file' (/home/myra/.cpanplus/5.16.0/build/Alien-SmokeQt-188.8.131.52/Makefile) is of invalid type for 'CPANPLUS::Dist::MM::_find_prereqs' provided by CPANPLUS::Dist::MM::prepare at /usr/share/perl5/core_perl/CPANPLUS/Module.pm line 823.
[ERROR] Unable to scan '/home/myra/.cpanplus/5.16.0/build/Alien-SmokeQt-184.108.40.206/Makefile' for prereq
The key part here is "Makefile is of invalid type". The Makefile shouldn't try to run cmake to determine the dependencies.
