MarsSeed [1] filed a deletion request for qtraw [2]: Discontinued; this last released version is from 2015. [a] Not compatible with Qt 5.15 and likely libraw 0.19+ (2019). (I tested this locally with Qt 5.15.11 and libraw 0.19 and current 0.21.1 from repo: fails RAW image read test.) Repo got migrated to Gitlab and abandoned since 2020. [b] From the latter source, master branch code passes file read tests with libraw 0.19.3 and 0.21.1, but does not pass a test for qt5-base 5.15.11's QImageReader error handling API.
