Failed to build with Qt 5.8

[yan12125]

1. Which version of PhantomJS are you using? Tip: run phantomjs --version.
   git-master

2. What steps will reproduce the problem?
   i. git clone https://github.com/ariya/phantomjs && cd phantomjs
   ii. qmake
   iii. make
   There's a compilation error:

$ make
cd src/qt-qpa-platform-plugin/ && ( test -e Makefile.phantom || /usr/bin/qmake -o Makefile.phantom /home/yen/Projects/tmp/phantomjs/src/qt-qpa-platform-plugin/phantom.pro ) && make -f Makefile.phantom 
Info: creating stash file /home/yen/Projects/tmp/phantomjs/src/qt-qpa-platform-plugin/.qmake.stash
Project ERROR: Unknown module(s) in QT: platformsupport-private
make: *** [Makefile:44: sub--home-yen-Projects-tmp-phantomjs-src-qt-qpa-platform-plugin-phantom-pro-make_first-ordered] Error 3

3. Which operating system are you using?
   Arch Linux

4. Did you use binary PhantomJS or did you compile it from source?
   Compile it from source

5. Please provide any additional information below.
   Latest Arch Linux ships with Qt 5.8. Apparently platformsupport-private is removed in Qt 5.8: http://stackoverflow.com/a/42198738/3786245

I ask Vitaly about it. Qt5.8.0 file structure changed and not supported in phantomjs. You need qt5.7.1 and build webkit from annulen branch.

Thanks. Is Qt 5.8 going to be supported in release 2.5? I see "Use system-installed Qt 5" is listed as a goal in #14458. As all other components on my system use Qt 5.8, it would be great to have PhantomJS running with it as well.

FWIW, here are my changes for building PhantomJS against Qt 5.8:

If I understand correctly, there won't be a v2.5. But still believe and hope someone or company is stepping up to take over the baton from PhantomJS maintainer Vitaly.
