=head1 NAME
dh_qmlcdeps - generate proper dependencies for QML cache files
=head1 SYNOPSIS
B<dh_qmlcdeps> [S<I<debhelper options>>]
=head1 DESCRIPTION
B<dh_qmlcdeps> is a debhelper program that looks for F<*.qmlc> files
(generated by B<qmlcachegen>) in the package temporary locations, performs
sanity check on them, and adds a dependency on B<libqt5qml5> package to
B<${qmlc:Depends}> substitution variable to make sure its version matches
the Qt version in these files.
You can pass B<--with qmlcdeps> to L<dh(1)> to make it automatically call
B<dh_qmlcdeps> after B<dh_install>.
