This is needed by Alkimia which I'm going to package soon as part of
KMyMoney.

I enabled this by default, because it doesn't increase the closure size
a whole lot (only around 150 KiB):

$ nix-store -q --size /nix/store/...old...-mpir-3.0.0
1223248
$ nix-store -q --size /nix/store/...new...-mpir-3.0.0
1377136

Introducing an option for enabling/disabling this is not worth it,
because it doesn't conflict with anything and the size increase is the
only drawback and we can still make it configurable if we want someday.

This is one of the requirements of KMyMoney and packaging is quite
straightforward with no unexpected traps.

This is used by KMyMoney and also the reason why I needed to add C++
support to MPIR in the parent commit.

The reason why I didn't add myself as a maintainer is because I'm not
personally using KMyMoney and thus Alkimia.

I tried to use -DENABLE_SQLCIPHER and also passed the right directories
to the Qt 5 source of the QSQLiteDriver but CMake then failed to run
qt4_automoc, by which I'd imply that SQLCipher is not maintained
anymore (after all KMyMoney using qgpgme as well, which doesn't require
sources).

Another odd thing is that CMake reports that the weboob plugin is
disabled, but after inspecting it turns out that the reporting is just
wrong. This is already fixed upstream but not yet released in
KDE/kmymoney@8b086cf.

In addition of running the upstream test suite I have manually tested a
few things in a VM by using the following Nix expression:

  (import <nixpkgs/nixos> {
    configuration = { pkgs, ... }: {
      environment.systemPackages = with pkgs; [
        kmymoney aqbanking gwenhywfar libchipcard python2Packages.weboob
        kgpg
      ];
      users.users.test.isNormalUser = true;
      virtualisation.diskSize = 4096;
      virtualisation.memorySize = 2048;
      services.xserver = {
        enable = true;
        inherit ((import <nixpkgs/nixos> {}).config.services.xserver) layout;
        displayManager.sddm.enable = true;
        displayManager.sddm.autoLogin.enable = true;
        displayManager.sddm.autoLogin.user = "test";
        desktopManager.default = "plasma5";
        desktopManager.plasma5.enable = true;
      };
    };
  }).vm

The things I have tested in particular are:

  * Basic startup
  * Completing the wizard
  * Add some test transactions
  * GPG encryption
  * Generation of charts and reports
  * Rough check whether OFX integration lists supported financial
    institutions.
  * Small check of AqBanking implementation, whether accounts and users
    can be configured, but didn't test actual connectivity with a
    financial institution.
  * Check of Weboob integration with a test PayPal backend, however also
    just with a dummy account and without actually connecting to PayPal.

One of the upstream tests "reports-chart-test" seems to fail even though
generating charts and reports are working when testing manually. It also
seems that this is the case on other distributions, for example Gentoo
has disabled that test as well:

https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=5169cec68fa6fd67841

Note that I didn't add myself as a maintainer because I'm not personally
using KMyMoney but just packaged it for someone else. I hope this is
useful for other people, so that maybe someday[TM] there will be a
proper maintainer.

   Maybe copy-paste the upstream "Alkimia is the infrastructure for
   common storage and business logic that will be used by all financial
   applications in KDE. The target is to share financial related
   information over application bounderies." as longDescription for
   Alkimia? The current description makes me want to look up the
   homepage to find out what it actually is (then I do, and despair).

This adds KMyMoney, a finance manager for KDE plus a few required
dependencies.

I ran the upstream test suite as well as the following manual tests:

  * Basic startup
  * Completing the wizard
  * Add some test transactions
  * GPG encryption
  * Generation of charts and reports
  * Rough check whether OFX integration lists supported financial
    institutions.
  * Small check of AqBanking implementation, whether accounts and users
    can be configured, but didn't test actual connectivity with a
    financial institution.
  * Check of Weboob integration with a test PayPal backend, however also
    just with a dummy account and without actually connecting to PayPal.

On top of that, the application already is being used by the person
requesting me to package this, so I'd guess it works well enough.

I'm merging this without the review from @ttuegel because it only adds
packages and doesn't change anything fundamental about the KDE
ecosystem.

The only change here is to add C++ support to "mpir", where the
maintainer (@7c6f434c) has approved the change.
