# Autotools-style (./configure) wrapper for CMake
# <https://github.com/nemequ/configure-cmake>
#
#   *** IMPORTANT ***
#
#   You must include the GNUInstallDirs module (which comes with
#   CMake) in your project.  Just put "include (GNUInstallDirs)" in
#   you CMakeLists.txt and you should be good.

# This script was originally written for Squash
# <https://quixdb.github.io/squash/> by Evan Nemerson

# though I would appreciate it if you would post improvements, bugs,
