you know how you can endorse people's skills on linkedin? they should offer a way to offer condolences for skills too
completely unrelated to that, i think i became twitter's residential cmake expert
recently at work I had to debug a qmake build problem around whitespace on windows and found a feature so obscure there were a total of zero google hits for it yet it solved my problem exactly - and it was fun, is this bad
basically, qmake has four documentation levels: documented, undocumented (https://wiki.qt.io/Undocumented_QMake…), very undocumented (you may find odd codebases on the net using this feature), and "you have to execute the build system in your head to come up with this"
I didn't have to steep that low myself, I ended up using a single somewhat elegant QMAKE_FUNC_FILE_IN_<function_name> construction where if I mentioned it now, this tweet would be the only google hit
