[icedtea-web] - problems configuring with: --disable-plugin

[Treutwein Bernhard]

hopefully this is the right place to ask also a question (if not, please let me know):

I am trying to build the netx.jar from the 1.7.1 sources. I do not need any plugin support,
so I tried to do a

./configure --disable-plugin

and arrived at the following error message:

[...]
checking for MOZILLA... no
checking for MOZILLA... no
configure: error: Package requirements (mozilla-plugin) were not met:

No package 'mozilla-plugin' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables MOZILLA_CFLAGS
and MOZILLA_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
------------------

Why should I have a package "mozilla-plugin" if the plugins are diabled?

What should I install? 

I am using a Debian 9.5 (stretch) based distribution (Q4OS). I had other errors
before this one, which I was able to resolve by installing several additional 
packages and/or creating some symbolic links and using --disable-plugin.

Regards and thanks in advance for any help
