Configuring incomplete, errors occurred!

[navdeepghai1]

I am getting errors while installing building Icinga Package from Github.

I followed these step to create user and user groups.

addgroup -S icinga

addgroup -S icingacmd

adduser -S -D -H -h /var/spool/icinga2 -s /sbin/nologin -G icinga -g icinga icinga

adduser icinga icingacmd

But I don't know how to use below command to replace www-data with your web-server user.
I don't what's name of my web server user is.
usermod -a -G icingacmd www-data
Make sure to replace "www-data" with the name of the user your web server is running as.

Now I am getting errors while building packages.
Building Icinga 2

Once you have installed all the necessary build requirements you can build Icinga 2 using the following commands:

$ mkdir build && cd build
$ cmake ..
$ make
$ make install

While executing cmake .. command I am getting this error.

Consider using packages. The Icinga documentation has a chapter which explains how to install Icinga: https://www.icinga.com/docs/icinga2/latest/doc/02-getting-started/
