[libvirt PATCH] m4: libxl: properly fail when libxl is required

Posted by Ján Tomko 4 years, 9 months ago

We specify "true" as the fail-action for LIBVIRT_CHECK_PKG.

This was used when we had a fallback to non-pkg-config detection,
then removed in commit 5bdcef13d13560512c7d6d8c9e8822e456889e0c
later re-introduced in commit dc3d2c9f8c7678a950abedd227b1587ca62335c4
and then left in when removing the old detection again in
commit 18981877d2e20390a79d068861a24e716f8ee422

Remove it to properly error out when libxl was requested but not
detected.
