# The directory containing the lzma binaries.

# Overrides the default library name.

# The directory containing the lzma headers.

# If none of these options is specified, then the environmental

#
# Examples::
#
# # Find lzma in the default system location
# using lzma ;
# # Find lzma in /usr/local
# using lzma : 1.2.7
# : /usr/local/include /usr/local/lib ;
