[QGIS-Developer] QGIS master branch fails make install on macOS 10.12.6

[Joel Buckley]

You're right, running `make clean` and starting the process again had it
all working. Thanks!

So the only remain hang-up I have, is that upon launch (of either the
standalone binary, or the `make`d launcher), I get the following error:
---
Couldn't load PyQGIS.
Python support will be disabled.


Traceback (most recent call last):
  File "", line 1, in
  File "/Users/joel/Documents/QGIS/build/output/python/qgis/gui/__init__.py", line 27, in
    from qgis._gui import *
ModuleNotFoundError: No module named 'PyQt5.Qsci'
---

I have searched on this, and tried reinstalling Qscintilla2 (via
homebrew). I've tried grepping for Qsci to determine if it's not being
picked up, but I'm not familiar enough with the build process just yet
to tell why it mightn't be compiled in.

Thanks for your help so far, and I hope this is my last query for now -
any suggestions on this error?

If it helps, I am running the following cmake:
cmake -D CMAKE_INSTALL_PREFIX=~/Applications \
-D CMAKE_BUILD_TYPE=MINSIZEREL \
-D ENABLE_TESTS=TRUE \
-D SPATIALINDEX_LIBRARY=/usr/local/lib/libspatialindex.dylib \
-D SPATIALINDEX_INCLUDE_DIR=/usr/local/include/spatialindex \
-D QWT_LIBRARY=/usr/local/Cellar/qwt/6.1.3_4/lib/qwt.framework \
-D QWT_INCLUDE_DIR=/usr/local/Cellar/qwt/6.1.3_4/lib/qwt.framework/Headers \
-D BISON_EXECUTABLE=/usr/local/bin/bison \
-D PYTHON_EXECUTABLE=/usr/local/bin/python3 \

-D GRASS_INCLUDE_DIR7=/usr/local/Cellar/grass7/7.2.1/grass-base/include \
-D GRASS_PREFIX7=/usr/local/Cellar/grass7/7.2.1/grass-base/ \
-D QSCINTILLA_LIBRARY=/usr/local/lib/libqscintilla2_qt5.dylib \
-D QSCINTILLA_INCLUDE_DIR:PATH=/usr/local/include \
..
