Cannot compile qtmqtt with a customized Qt5 install path

We use in production a Cento6 Linux computer 64 bits where Qt4.6 is only available officially.

To use a more recent version of Qt, i compiled and installed Qt5.14.2 official tarball we only few components need for the target application as core, gui, widgets, svg, websockets, serialports. We don't use qml and webengine components.

Qt5 is installed in a customized path in a home directory. We compile and run fine the target application use CMake, not qmake.

 

/home/det/Documents/gilles/installqt/qt5/bin/qmake -query

We want to experiment the qtmqtt extra component and i started to try to compile this code using the fresh install of Qt5.14.2. It do not work. This is my bash script used to compile qtmqtt :

 

 /opt/rh/devtoolset-8/enable

 

export Qt5_DIR=/home/det/Documents/gilles/installqt/qt5

export PATH=/home/det/Documents/gilles/installqt/qt5/bin/:$PATH

export QT_QMAKE_EXECUTABLE=/home/det/Documents/gilles/installqt/qt5/bin/qmake

rm -rf build

mkdir build

cd build

qmake ..

cd build

make

 

This is the result of compilation :

In fact, at make, the qtmqtt API headers are not generated in build directory. If i take another computer with Centos 8 and the system based Qt 5.12, the same qtmqtt code compile fine :

 

[gilles@localhost qtmqtt]$ make

Under Centos6 it miss some stage to configure create modules header files. Why ? What's missing exactly ?

 

Thanks in advance for your help.

 

PS : I also cross compiled Qt 5.14.2 + qtmqtt 5.14.2 for WebAssembly (really nice target, congratulations) under CentoS8, and all compile fine too. So i'm sure that my cento6 + qt 5.14.2 has some wrong, but what ?
