# - Find PHP4
# This module finds if PHP4 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:
#
#  PHP4_INCLUDE_PATH       = path to where php.h can be found
#  PHP4_EXECUTABLE         = full path to the php4 binary
#
