-PKG_CHECK_MODULES(
-    [PHOSPHOR_LOGGING],
-    [phosphor-logging],
-    [],
-    [AC_MSG_ERROR([Could not find phosphor-logging...openbmc/phosphor-logging package required])])
-```
-
-### Description
-
-The autotools PKG_CHECK_MODULES macro provides the ability to specify an "if
-found" and "if not found" behavior. By default, the "if not found" behavior will
-list the package not found. In many cases, this is sufficient to a developer to
-know what package is missing. In most cases, it's another OpenBMC package.
-
-If the library sought's name isn't related to the package providing it, then the
-failure message should be set to something more useful to the developer.
-
-### Resolution
-
-Use the default macro behavior when it is clear that the missing package is
-another OpenBMC package.
