I am pleased you have your situation sorted.
Purely OOI, because I like shell scripting, why did you bother to put the xargs into your command when
dpkg -l | grep qt | awk '{print $2}'
would deliver the same result? :) | xargs -n1 echo is a bit of a no-op?

Just to make sure you understand.
When you install Qt from Qt site you get the normal version.
However, Unbuntu also allows you to use apt-get an Qt version. ( often Not the newest but close)
If you use that version, then you can also apt-get thd MySql stuff that is compiled with the unbuntu version of Qt.
So ifs not critical to use the absolute newest Qt then
Remove the version from Qt site
and apt-get Qt from ubuntu and the MySql Stuff and it should just work with no extra effort.

Thanks @SGaist, your answer made me remove everthing and try the OCV version that is provided by Ubuntu 18.04. I got 3.X.X from there... After I removed this version again (because I want a newer one) and installed 4.1 from OCV page, it worked :-)

It uses compiler_version.py, too.
In my case, near line 54, the below source codes exist:
def GetVersion(compiler, tool):
  tool_output = tool_error = None
  cache_key = (compiler, tool)
  cached_version = compiler_version_cache.get(cache_key)
  if cached_version:
    return cached_version
  try:
    # Note that compiler could be something tricky like "distcc g++".
    if tool == "compiler":
      compiler = compiler + " -dumpversion"
      # 4.6
      version_re = re.compile(r"(\d+)\.(\d+)")

Maybe, from g++(or gcc) version 7, -dumpversion option shows only major version such as 7, so that the regular expression of compiler_version.py raises an exception because it expects the version including minor one.
So, I modified the option from -dumpversion to -dumpfullversion, and then it works well.
