[Qgis-developer] Building QGIS2.99 cloned from GitHub on Ubuntu 16.10 (yakkety) 64-bit Python

[gordon at shieldaig.com]

This is what I changed to get what I had to build on Ubuntu 16.10.  I am 
using the free open source version of Qt directly from their website.

1.  I used the Qt Maintenance tool to install a local copy of Qt 5.7.1, 
to be consistent with `pyqt5-dev`, `pyqt5-dev-tools` and some other 
python packages, and modified `ccmake ..` to use it except for Qt5WebKit 
and Qt5WebKitWidgets which remained as configured.  That means in the 
ccmake I changed the path from Qt5Concurrent_DIR to Qt5Xml_DIR to 
`/home/<my username>/Qt/5.7/gcc_64/lib/cmake/...`

2.  I modified `qendian.h` in the Qt 5.7 folder `include/QtCore` I made 
beginning section of the Qt 5.7 file the same as Qt 5.6 for 
QT_HAS_BUILTIN ie.

`#ifdef __has_builtin
#  define QT_HAS_BUILTIN(x)     __has_builtin(x)
#else
#  define QT_HAS_BUILTIN(x)     0
#endif`

3.  In folder QGIS/src/core/qgis.h I added the line `#include 
<QIODevice>` before all other includes.  This eliminate a problem with a 
`isTransactionStarted` missing member of IODevice Class.  I did this 
because the header said must be included before any `open`.

4.  In folder QGIS/src/gui/qgisgui.h I added the line `#include 
<QIODevice>` before all other includes.  This eliminate a problem with a 
`isTransactionStarted` missing member of IODevice Class.

5.  In folder QGIS/src/gui/qgshelp.h I added the line `#include 
<QIODevice>` before all other includes.  This eliminate a problem with a 
`isTransactionStarted` missing member of IODevice Class.

Hopefully these changes will point the development team or someone to 
problems building on Ubuntu 16.10 64-bit - I did a full upgraded to it 
from 16.04 just a few days ago.  I did install `geos` 3.6 from source 
but that probably made little difference but a fix of that issue is now 
on Github.

The build continued until:
`[ 94%] Linking CXX shared library ../../output/lib/libqgis_app.so
[ 94%] Built target qgis_app`

There may have been an easier way but I didn't know what it was.  I am 
not that familiar with Qt.  I haven't resolve the db_manager issue.  
Anyone know how to fix that?
