    This PR reworks the way Qt dependency is built :-

    1. Introduces a top level config/build which
    2. Simplifies the way Qt is built, removing confusing lines
    3. Resolves static build for #16883
    4. Mimic how Qt is built from repo/all-in-one
    5. Is related to bitcoin#20504 which makes (q)make commands simpler
    6. Continuation/Completion of https://github.com/icota/bitcoin/commit/683710e072eb90296ae5a57f53bce7cac799fc41 which had incomplete dependency chain.

    While trying to add Qml/QtQuick i took a closer look at how QT builds and found that it uses a top level qt.pro which by far simplifies the build process.

  2. Add QML/ QtQuick Depends ef283d513d
  3. Start using top level Qt for depends 633660c529

    The ci doesn’t pass, but this looks like a major rewrite, so it would be better to wait for some Concept ACKs from the build people

    Seven, to the Build People, great miners and craftsmen of the mountain halls.

    Concept ACK on adding support for Qml/QtQuick. Haven’t studied the code in deep but the submodule part seems messy.

    I’m not entirely sure what this does. Does this make qt submodules of our repository?
    BlockMechanic commented at 1:34 pm on December 10, 2020:
    Hi, No, it does not make qt submodule of bitcoin. The file is just used by qt.pro to determine which qt modules to build, and what their dependencies are. Perhaps, i can rename the file to prevent confusion ?

    Concept ACK but:

    • changing the way we build Qt and (subsequent) enabling of QML modules should probably be two separate PRs
    • .configure is a script so doesn’t really belong in patches (actually none of the added files do)

    Yeah, none of them are strictly patches. I was avoiding making a separate folder to maintain general logic/structure.

    icota commented at 2:12 pm on December 10, 2020:
    This files looks to be stripped of its licence (LGPL). It’s better to extract the file (and others) directly from the submodules. If the files have been slightly modified from the Qt source add a patchfile - to be in line with the current practice.
    BlockMechanic commented at 2:53 pm on December 10, 2020:
    These specific files are not within the submodules unfortunately nor are they listed in the download directory see :- https://download.qt.io/official_releases/qt/5.9/5.9.8/submodules. They are only in the all-in-one or the git, so I had copied them separately to avoid downloading the whole all-in-one only to extract these three files and then duplicate the work by separately downloading each module.
    icota commented at 5:34 pm on December 10, 2020:
    In that case I vote for downloading the all-in-one. It would reduce this PR by three files and most of its lines. It would also simplify existing code. The download would take a bit longer but if we want QML I think it’s worth it.
    promag commented at 5:53 pm on December 10, 2020:
    I’m already working on that approach @icota. Also worth noting that single file was the old approach, and it was changed in ab67dd7818ff2d0910f3fd9bfca9412d85de4424, maybe @theuni had a motivation for using modules.
    BlockMechanic commented at 7:26 pm on December 10, 2020:
    @promag I have an all in one build already functional, should i open a PR and we collaborate ?
    promag commented at 7:45 pm on December 10, 2020:
    @BlockMechanic sure! Happy to review and compare with my change.

    The first part is implemented in #20641.

    I’m not a fan of this approach. It’s also unclear exactly what’s going on, or why this is being done this way from a quick glance, as most of the commits have no useful title or description. I’m going to close this in favour of #20641, as it seems that achieves the same goal, and is going to be far more maintainable in the long term.
