# CS_CHECK_LIBTOOL
|
|
# Find and identify the various implementations of libtool. In
|
|
# particular, this macro is aware of GNU libtool and Apple's libtool
|
|
# (which serves a completely different purpose). On MacOS/X, GNU libtool
|
|
# is typically named glibtool, however a user might also use Fink to
|
|
# install the unadorned libtool; and the Fink-installed version might
|
|
# shadow Apple's own libtool if it appears in the PATH before the Apple
|
|
# tool. This macro jumps through the necessary hoops to distinguish and
|
|
# locate the various implementations. Sets the shell variable LIBTOOL to
|
|
# the located GNU libtool (if any), and APPLE_LIBTOOL to the located
|
|
# Apple libtool. Invokes AC_SUBST() for LIBTOOL and APPLE_LIBTOOL.
