libvirt users - Mar 2015 - No package 'libvirt' found

Hi,
  After successful libvirt compilation on Cygwin, I am trying to run virt-manage
which requests LibvirtGLib:
$ virt-manager

Traceback (most recent call last):

  File "/usr/share/virt-manager/virt-manager", line 30, in
<module>

    from gi.repository import LibvirtGLib

ImportError: cannot import name LibvirtGLib

  I understand that I need to compile libvirt-glib.  The problem is that I get
the following error once running ./configure:

checking whether C compiler handles -fexceptions... yes

checking whether C compiler handles -fasynchronous-unwind-tables... yes

checking whether C compiler handles -fipa-pure-const... yes

checking whether C compiler handles -Wno-suggest-attribute=pure... yes

checking whether C compiler handles -Wno-suggest-attribute=const... yes

checking for pkg-config... /usr/bin/pkg-config

checking pkg-config is at least version 0.9.0... yes

checking for LIBVIRT... no

configure: error: Package requirements (libvirt >= 0.10.2) were not met:


No package 'libvirt' found


Consider adjusting the PKG_CONFIG_PATH environment variable if you

installed software in a non-standard prefix.


Alternatively, you may set the environment variables LIBVIRT_CFLAGS

and LIBVIRT_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

  The only "libraries" I have been able to find are:

$ cp /usr/local/bin/cygvirt-

cygvirt-0.dll       cygvirt-lxc-0.dll   cygvirt-qemu-0.dll

  Copying it to /usr/lib doesn't change anything.  Renaming these files from
cygvirt* to libvirt* either.
  Any idea?
