[kdenlive] build script ver 27

[Roger Morton]

Vincent has released an updated version of "the build script" - ver 27 see
http://www.mltframework.org/twiki/bin/view/MLT/BuildScripts#Kdenlive
This version builds against KF5 version of the KDE frameworks so
should  work with ver 15.N of kdenlive
However, in my hands it fails.
First up it looks like latest git version of kdenlive needs a newer
version of KF5 because when running against the head of the kdenlive
git tree I get version failures on a bunch of KF5 pacakges.
But I can get past that problem by doing

KDENLIVE_HEAD=0
KDENLIVE_REVISION=remotes/origin/Applications/15.12

But in that configuration I get this error:

-- Configuring done

ERROR: Unable to build kdenlive
LOG: Process has finished. Reason: FAILURE Some kind of error occured:

My version 26b of the build script at
https://community.kde.org/index.php?title=Kdenlive/Development/KF5#A_build_script
works still for me. A major difference between the two is this use of
a DQT_QMAKE_EXECUTABLE var in the config command

ver26b
QMAKE=`kf5-config --qt-binaries`/qmake
CONFIG[2]="cmake -Wno-dev -DCMAKE_INSTALL_PREFIX=$FINAL_INSTALL_DIR
-DCMAKE_BUILD_TYPE=debugfull -DQT_QMAKE_EXECUTABLE=$QMAKE"

ver27
  CONFIG[2]="cmake .. -DCMAKE_INSTALL_PREFIX=$FINAL_INSTALL_DIR
-DCMAKE_BUILD_TYPE=RelWithDebInfo"

I am going to test ver27 with a DQT_QMAKE_EXECUTABLE parameter and see
if that fixes that version for me.
