# This file is loaded by some qmakespecs to get early configuration data.
nuke configure -host-option in its current form, it was introduced only in 5.7, mostly as a side effect of -external-hostbindir (which is now handled differently). it only ever worked for the macOS and MinGW specs, as a side effect of them supporting -sdk and -device-option (for good reasons), and was supported only by the unix configure. it's not believed to be really useful and complicates matters somewhat, so get rid of it again. should it ever become actually relevant, it can be re-introduced properly, probably along with a -host-sdk option for macOS.

device: Add -device and -device-option to configure For some reference platforms and SDKs we will need to pass in extra paths. Currently users have to modify the mkspec to adjust paths or set environment variables that will be picked up. This change introduces the -device <name> and -device-option <key=value> option. The key value pairs will be written to a qdevice.pri and can be used by the qmake.conf of the device spec. The reason to not save the key value pairs in qconfig.pri is becase of the fact that the device spec loads the qdevice.pri earlier than the qconfig.pri. qdevice.pri allows the mkspec to set the compiler flags and qconfig.pri allows configure to add to those compiler flags.

configure: Separate host and build platform. This separation makes it possible to make a canadian cross build of Qt on a linux build machine. The canadian cross build requires an external Qt that runs on the build system.
