# Initializes the zlib library.
#
# zlib can be configured either to use pre-existing binaries
# or to build the library from source.
#
# Options for configuring a prebuilt zlib::
#
#
# The directory containing the zlib binaries.
#
# Overrides the default library name.
#
# The directory containing the zlib headers.
#
# If none of these options is specified, then the environmental
# variables ZLIB_LIBRARY_PATH, ZLIB_NAME, and ZLIB_INCLUDE will
# be used instead.
#
# Options for building zlib from source::
#
#
# The zlib source directory. Defaults to the environmental variable
# ZLIB_SOURCE.
#
# A rule which computes the actual name of the compiled
# libraries based on the build properties. Ignored
# when using precompiled binaries.
#
# The base name to use for the compiled library. Ignored
# when using precompiled binaries.
#
# Examples::
#
# # Find zlib in the default system location
# using zlib ;
# # Build zlib from source
# using zlib : 1.2.7 : /home/steven/zlib-1.2.7 ;
# # Find zlib in /usr/local
# using zlib : 1.2.7
# : /usr/local/include /usr/local/lib ;
# # Build zlib from source for msvc and find
# # prebuilt binaries for gcc.
# using zlib : 1.2.7 : C:/Devel/src/zlib-1.2.7 : msvc ;
# using zlib : 1.2.7 : : gcc ;
