Cannot get "shadow build" to compile
I want to do a "shadow build" of QT 5.5.1 for msvc 2015, by following the instructions in http://doc.qt.io/qt-5/configure-options.html, so that I can build both release and debug libraries in separate locations. However, when I follow those instructions to the best of my ability, I get compilation errors saying that QtCore/qconfig.h cannot be found.
Has anyone written up instructions that a newbie to Qt compiling can **actually **follow to build in this manner? I know it is difficult to write instructions like that, but surely it is not impossible.
Apparently "shadow build" isn't working for 5.5.1, at least with VS 2015. Here are apparently correct instructions on how to build Qt, for people who don't already know how to do it:
Out of curiosity, what didn't work for you ?
