Using a CMAKE Build dh_auto_configure: says in Launchpad failed to to execute: No such file or directory

Well in my PPA https://launchpad.net/%7Eanton+/+archive/ubuntu/photo-video-apps/ I tried to build jasper packages.

It is building fine on my system Xenial 16.04 where I get for dh_auto_configure at build time:

make[1]: Entering directory '/home/ubuntu-xenial/pascal/Downloads/Launchpad/jasper/jasper-2.0.14'
dh_auto_configure -- \
 -DCMAKE_INSTALL_PREFIX=/usr \
 -DCMAKE_BUILD_TYPE=Release \
 -DCMAKE_SKIP_INSTALL_RPATH=YES \
 -DJAS_ENABLE_DOC=NO \
 -DJAS_ENABLE_SHARED=YES

However building for Trusty 14.04 in Launchpad I get the following
https://launchpadlibrarian.net/394560072/buildlog_ubuntu-trusty-amd64.jasper_2.0.14-1pmo1.0~trusty_BUILDING.txt.gz

Why is that such a difference ? And an error aborting the build for all Ubuntu releases ?
Is it because of the --parallel build ?

I've never seen that before.
