I finally found the problem.
The libraries "libusb" and "libftdi" and some other libraries, were not 
installed.
I don't know, why they were skipped when using the workflow from the homepage.
I rebuilt libsigrok and now configure shows, that fx2lafw is enabled.

Unfortunately the shared library libsigrok.so.3 is now missing.
I will try to find out why.


Thank you for your support.

Thank you for your help.

I rebuilt libsigrok with switches
        ./configure --enable-fx2lafw
        make
        sudo make install

Unfortunately this did not change anything. I still get the error.
Do I have to remove the old stuff first?
I quite never understood how to remove self-compiled software.

You need to rebuild libsigrok with appropriate switches. Either do not use 
--disable-all-drivers (as --enable-all-drivers should be the
default) or add --enable-fx2lafw (and the others you might need) to ./configure 
invocation.

It'll get uploaded automatically by the driver when you first try to use it.
