    Description

      How to reproduce

      • install Qt with the installer
      • qt-configure-module some other Qt module (qtsvg for example) with that installed Qt

      What happens

      CMAKE_INSTALL_PREFIX is set to /Users/qt/work/install which is the install prefix on the packaging machine

      What should happen

      CMAKE_INSTALL_PREFIX should be the actual installation location of Qt.

      Notes

      This happens, because QtBuildInternalsExtras.cmake contains the hard-coded value /Users/qt/work/install:

      if(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT AND
   NOT QT_BUILD_INTERNALS_NO_FORCE_SET_INSTALL_PREFIX)
    set(CMAKE_INSTALL_PREFIX "@CMAKE_INSTALL_PREFIX@" CACHE PATH
        "Install path prefix, prepended onto install directories." FORCE)
endif()

      possible solution is

      if(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT AND
   NOT QT_BUILD_INTERNALS_NO_FORCE_SET_INSTALL_PREFIX)
    set(CMAKE_INSTALL_PREFIX "${QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX}" CACHE PATH
        "Install path prefix, prepended onto install directories." FORCE)
endif()

      but we need to double-check all implications.
