TEA_MAKE_LIB
#--------------------------------------------------------------------
# Find tclsh so that we can run pkg_mkIndex to generate the pkgIndex.tcl
# file during the install process. Don't run the TCLSH_PROG through
# ${CYGPATH} because it's being used directly by make.
# Require that we use a tclsh shell version 8.2 or later since earlier
# versions have bugs in the pkg_mkIndex routine.
# Add WISH as well if this is a Tk extension.
#--------------------------------------------------------------------
TEA_PROG_TCLSH
#--------------------------------------------------------------------
# Finally, substitute all of the various values into the Makefile.
# You may alternatively have a special pkgIndex.tcl.in or other files
# which require substituting th AC variables in. Include these here.
