问题
Since I found no answer for my question, neither in older posts nor in other forums, I want to ask the stackoverflow community for advice.
I am using a raspberry pi 3B+, version 9.4 (lite) with kernel version 4.14.71-v7.
I use python3.6. I installed it as follows:
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
cd /usr/src
sudo wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
sudo tar xzf Python-3.6.0.tgz
sudo -s
cd Python-3.6.0
bash configure
make altinstall
exit
Installation was without any trouble and everything works perfectly.
Now I wanted to install the PyQt5 modul for python3.6. I usually use
sudo python3.6 -m pip install ...
for installing a modul for python3.6. Trying
sudo python3.6 -m pip install pyqt5
gave me the error message
Could not find a version that satisfies the requirement PyQt5 (from versions: )
No matching distribution found for PyQt5
So I tried
sudo apt-get update
sudo apt-get install qt5-default pyqt5-dev pyqt5-dev-tools
But it installed PyQt5 for python3.5 (which is preinstalled) on the raspberry.
So does anybody know how to use or install PyQt5 for the subsequently installed python3.6?

Thanks FlyingTeller. I started to build from source. I followed the steps from
your link.
sudo apt-get update
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/sip-4.19.14.tar.gz
sudo tar xzf sip-4.19.14.tar.gz
cd sip-4.19.14
sudo -s
python3.6 configure.py --sip-module=PyQt5.sip
make
make install
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/PyQt5_gpl-5.12.tar.gz
sudo tar xzf PyQt5_gpl-5.12.tar.gz
cd PyQt5_gpl-5.12
python3.6 configure.py
Then I received the following error
Error: Use the --qmake argument to explicitly specify a working Qt qmake.
I think I am on the right way, but I do not understand what qmake is or what it means.
Edit 10.03.2019:
I could solve the last error message. I installed
sudo apt-get install qt5-default
Then I did the same procedure as already mentioned. Now I get the error
fatal error: sip.h: File or directory not found
#include <sip.h>
PyQt5 config.py is in: /usr/src/PyQt5_gpl-5.12
SIP sip.h is in: /usr/src/sip-4.19.14
Anybody an idea? Thanks guys.

Today I found the solution. The steps below worked for me, without any error. The whole process took almost two hours.
sudo apt-get update
sudo apt-get install qt5-default
sudo apt-get install sip-dev
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/sip-4.19.14.tar.gz
sudo tar xzf sip-4.19.14.tar.gz
cd sip-4.19.14
sudo python3.6 configure.py --sip-module PyQt5.sip
sudo make
sudo make install
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/PyQt5_gpl-5.12.tar.gz
sudo tar xzf PyQt5_gpl-5.12.tar.gz
cd PyQt5_gpl-5.12
sudo python3.6 configure.py
sudo make
sudo make install
