libvirt users - Mar 2021 - Regarding location of Libvirt library

Hi,
I have installed Libvirt 7.1.0.
I configured and built libvirt based on instructions from
https://libvirt.org/compiling.html.
Now I developed a client program to create a VM using an XML file.As the
API for it is *virDomainCreateXML,* called this API by passing XML file .It
shows the following error.
undefined reference to `virDomainCreateXML'.
I included the header files containing the said API declaration.But need to
include the library also.
My question is where do the libvirt library located after building it.
Thanks for the help in advance.

Yes, you need to pass -lvirt when linking. The library is installed 
wherever you told it to install. If you ran plain meson with no extra 
arguments, then 'meson install' installs library under /usr/local/lib/ 
or /usr/local/lib64/. So you will need to pass -L/usr/local/lib or 
-L/usr/local/lib64 too to the linker.

But there is this switch -Dsystem=true which tells meson to install into 
system directories:

   meson -Dsystem=true build
   meson install -C build

with this you will not need to pass any extra -L arguments to the linker.
