Compiling error on almalinux 8.7 : src/Makefile.am:9: error: 'vmod_LTLIBRARIES' is used but 'vmoddir' is undefined

Hi There , Trying to compile your storage engine in almalinux 8.7 with varnish 7.3 and getting this error :

src/Makefile.am:9: error: 'vmod_LTLIBRARIES' is used but 'vmoddir' is undefined

Steps :

• compiled the varnish 7.3.0 from source url is - wget https://varnish-cache.org/downloads/varnish-7.3.0.tgz and of course according to the instructions here - https://varnish-cache.org/docs/trunk/installation/install_source.html#compiling-varnish
• Trying to compile the slash and failed which cloned from - git clone https://code.uplex.de/uplex-varnish/slash.git
• i have exported the directory of varnish to the directy of varnish source which is export VARNISHSRC=/root/varnish-7.3.0/.
• excuted ./bootstrap or ./bootstrap VARNISHSRC=/root/varnish-7.3.0/ and in the beggining of the proccess i have received the folowing error any idea why ?

Thanks Dave
