[collectd] Collectd with NUT error

    Hello Florian!
    I had been tested last collectd-4.3.2 version and found that as in  
previous versions
i MUST use 'CPPFLAGS=-I/usr/local/ups/include' option with 'configure'  
script for compiling
collectd with 'libupsclient' support without following errors:

...
  gcc -DHAVE_CONFIG_H -I. -I. -I.

    Sorry, but i don't understand why we pointing NUT root directory twice  
so as
i use '--with-libupsclient=/usr/local/ups' option also and i think script  
can
make search for includes in it?
    Whom this bug?

    Thank you very much,
    Alex
