Issue #1)
brew link --force qt5

Prints this warning:

$ brew link --force qt5
Linking /usr/local/Cellar/qt5/5.6.1-1... 
Error: Could not symlink bin/lconvert
Target /usr/local/bin/lconvert
is a symlink belonging to qt. You can unlink it:
  brew unlink qt

To force the link and overwrite all conflicting files:
  brew link --overwrite qt5

To list all files that would be deleted:
  brew link --overwrite --dry-run qt5

Following this suggestion...

$ brew link --overwrite qt5
Warning: qt5 is keg-only and must be linked with --force
Note that doing so can interfere with building software.

Adding --force to --overwrite...

$ brew link --overwrite --force qt5

...seams to work.

Issue #2)

$ qmake && make && macdeployqt QtPass.app
Usage: qmake [mode] [options] [files]

QMake has two modes, one mode for generating project files based on
some heuristics, and the other for generating makefiles. Normally you
shouldn't need to specify a mode, as makefile generation is the default
mode for qmake, but you may use this to test qmake on an existing project

Mode:
  -project       Put qmake into project file generation mode
                 In this mode qmake interprets files as files to
                 be built,
                 defaults to *; *; *; *.ts; *.xlf; *.qrc
                 Note: The created .pro file probably will 
                 need to be edited. For example add the QT variable to 
                 specify what modules are required.
  -makefile      Put qmake into makefile generation mode (default)
                 In this mode qmake interprets files as project files to
                 be processed, if skipped qmake will try to find a project
                 file in your current working directory

Warnings Options:
  -Wnone         Turn off all warnings; specific ones may be re-enabled by
                 later -W options
  -Wall          Turn on all warnings
  -Wparser       Turn on parser warnings
  -Wlogic        Turn on logic warnings (on by default)
  -Wdeprecated   Turn on deprecation warnings (on by default)

Options:
   * You can place any variable assignment in options and it will be     *
   * processed as if it was in [files]. These assignments will be parsed *
   * before [files].                                                     *
  -o file        Write output to file
  -d             Increase debug level
  -t templ       Overrides TEMPLATE as templ
  -tp prefix     Overrides TEMPLATE so that prefix is prefixed into the value
  -help          This help
  -v             Version information
  -after         All variable assignments after this will be
                 parsed after [files]
  -norecursive   Don't do a recursive search
  -recursive     Do a recursive search
  -set <prop> <value> Set persistent property
  -unset <prop>  Unset persistent property
  -query <prop>  Query persistent property. Show all if <prop> is empty.
  -cache file    Use file as cache           [makefile mode only]
  -spec spec     Use spec as QMAKESPEC       [makefile mode only]
  -nocache       Don't use a cache file      [makefile mode only]
  -nodepend      Don't generate dependencies [makefile mode only]
  -nomoc         Don't generate moc targets  [makefile mode only]
  -nopwd         Don't look for files in pwd [project mode only]

Mandatory qmenu command line options are missing. Which options do we need?

$ qmake -v
QMake version 3.0
Using Qt version 5.6.1 in /usr/local/Cellar/qt5/5.6.1-1/lib

Please update documentation.

1. Updated in commit 89a05ce

2. The qmake mode is -makefile
   Put qmake into makefile generation mode (default)

But that is (normally) implicit.

You can try qmake qtpass.pro
