dnl LIBBYTESIZE_SOFT_FAILURE(MESSAGE)

dnl

dnl Store a message that in some contexts could be considered indicative

dnl of a failure, but in other contexts could be indicative of who cares.

dnl

dnl Any message sent to this macro will be stored, and they can all be

dnl displayed at the end of configure using the LIBBYTESIZE_FAILURES macro.

dnl LIBBYTESIZE_PKG_CHECK_MODULES(VARIABLE-PREFIX, MODULES)

dnl

dnl Check whether a module is available, using pkg-config. Instead of failing

dnl if a module is not found, store the failure in a message that can be

dnl printed using the LIBBYTESIZE_FAILURES macro.

dnl

dnl The syntax and behavior of VARIABLE-PREFIX and MODULES is the same as for

dnl PKG_CHECK_MODULES.
