[Libguestfs] [PATCH 1/3] build: fix the pkg-config identifier of the (optional) Yara library
The upstream Yara project has always provided its "libyara/yara.pc.in"
file with "Name: yara" -- ever since its introduction in commit
334bd1a671ca ("Add support for pkg-config", 2015-01-08).
In spite of this, when the (optional) Yara dependency was added to
libguestfs in commit 2e24129da376 ("appliance: add yara dependency",
2017-05-02), PKG_CHECK_MODULES was invoked with [libyara] as
list-of-modules.
(That was clearly a bug. I'm unsure what Debian calls their Yara
pkg-config module, but calling it anything else than "yara" would be a
distribution bug: upstream projects provide pkg-config files specifically
so that dependent projects can find their dependencies *regardless of
distribution*.)
As a consequence, on Fedora today, the PKG_CHECK_MODULES macro always
fails, and only the AC_CHECK_LIB / AC_CHECK_HEADER branch finds Yara.
In a subsequent patch, we'll want to add a version requirement to the
PKG_CHECK_MODULES macro invocation, so at first, fix the pkg-config
identifier of Yara.
