- Drop pkgconfig(libnm-glib) BuildRequires: Balsa switched from
libnm-glib to GNetworkMonitor in version 2.5.2.
- Drop pkgconfig(libsecret-1) BuildRequires: Not used, as we are
not passing --with-libsecret to configure (upstream default is
not using it).
- Stop passing --enable-smime, --with-gtkspell and --with-ssl to
configure, no longer recognized.
- Replace pkgconfig(gtkspell3-3.0) with pkgconfig(gspell-1)
BuildRequires and pass --with-spell-checker=gspell to configure.
This also allows for dropping conditionals for
pkgconfig(enchant-2) and pkgconfig(enchant) BuildRequires.
- Replace openssl-devel with pkgconfig(openssl) BuildRequires,
align with what configure checks for.
