Subject: autoconf: More informative errors when pkg-config macros undefined
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=41b00707e20f0c07e0dce055884c773de4b82612;p=mesa.git

autoconf: More informative errors when pkg-config macros undefined

Added a check that PKG_PROG_PKG_CONFIG is defined before calling it so
the user can see a proper error. Without it, the generated configure
script will just pass on to the next statement and bomb with a strange
shell syntax error.
