    When gitian building on Windows I'm seeing:

    checking for Qt 5... yes
checking for > Qt 5.7... yes
checking for main in -limm32... yes
checking for main in -lz ... yes
checking for library containing jpeg_create_decompress ... configure: WARNING: libjpeg not found. Assuming qt has it built-in
no
checking for library containing png_error ... -lqtlibpng
checking for library containing pcre2_match_16... -lqtpcre2
checking for library containing hb_ot_tags_from_script ... -lqtharfbuzz

    We are passing -qt-libjpeg to Qt: https://github.com/bitcoin/bitcoin/blob/e6e99d4f757f2e5052f0cc68951c75e91e4753e3/depends/packages/qt.mk#L66 but I dont think we are doing anything with jpeg related regardless?

    Concept ACK. IIRC we used some jpegs ages ago, but since removal this is overdue.

    Could you switch to the qt config to -no-jpeg as well? It shouldn't affect the end-result in any meaningful way because all of the unused jpeg stuff should be stripped out by the linker anyway, but we can at least avoid compiling libjpeg as part of the qt build.

    Concept ACK, agree that we should change the qt config to -no-jpeg, and also remove libjpeg from doc/dependencies.md

    Added -no-libjpeg to Qts configure flags, and removed jpeg from doc/dependencies.md. Also added a commit that removes the line numbers from the qt packages that we reference in there, as at the moment they are constantly incorrect.

    Good catch, I struggle to remember what we ever needed jpeg for, so I searched history:

     delete mode 100644 src/qt/res/images/splash2.jpg

    it was removed in 2013 in f9124587ccea723dbd743e3877a7071fbb6c5732

    ACK f509e3b8ce0c5652e85ce26545f7ed94689f46ab
