Yeah, after reading stuff on lua-users.org (IIRC), this is the (completely
untested) pkg-config-searching code I've got so far. <sigh>
~~~
# First, try the standard (pkg-config) way.
PKG_CHECK_MODULES(LUA, lua, [have_lua=yes], [have_lua=no])
# Unfortunately Lua's pkg-config file isn't standardly named.
# Apparently Debian, in particular, allows installation of
multiple
# versions of Lua at the same time (thus each version has its
own
# package name).
for ver in 5.2 -5.2 5.1 -5.1 5.0 -5.0
do
if test "x$have_lua" == "xyes"
then
# We're done here!
return
fi
PKG_CHECK_MODULES(LUA, lua$ver, [have_lua=yes],
[have_lua=no])
done
