+# 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

+# repository.  Please feel free to copy it into your own repository,
+# though I would appreciate it if you would post improvements, bugs,
+# feature requests, etc. to the issue tracker at
