# - Find Tcl includes and libraries.
# This module finds if TCL is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#  TCL_LIBRARY        = path to Tcl library (tcl tcl80)
#  TCL_LIBRARY_DEBUG  = path to Tcl library (debug)
#  TCL_INCLUDE_PATH   = path to where tcl.h can be found
#
# Several changes and additions by Fabian 'x3n' Landau
