This should imply some answers.
That would be a chicken-and-egg problem: Unless cmake has built-in qt support any knowledge about qmake would need to come from the Qt cmake module, which is supposed to be found by querying qmake... If cmake really has built-in qt support then a Qt5CoreConfig.cmake module would not be needed. > The 'find_package()' tries number of paths to find the appropriate > Qt5CoreConfig.cmake, searching cmake-module-paths, lib paths and also > going through the PATH variable. I had a look at https://cmake.org/cmake/help/v3.5/command/find_package.html. It is quite complicated (and intransparent IMHO), but there seems to be some magic that does indeed guess from bin directories in the PATH to corresponding lib/cmake directories. This seems to be used by build5-2915.bat as well, so I adjusted INSTALL.Win32 accordingly. Georg
