# By default, generate a self-contained build left where the build was run.
# If not using the Windows front end, the executable will have hardwired
# relative paths to the game's data, and when run, the working directory should
# be the location of executable.  The other options are to build for a shared
# installation with a setgid executable that manages the save and high score
# files or to build for a read-only installation where all the variable
# persistent state is stored in the user's directories.  Those two other
# options use paths from GNUInstallDirs as the basis for where stuff is
# installed.  Because paths are configured into the executable, it is not
# possible to set the destination dir when running make (i.e. with DESTDIR).
# One can set the paths when running cmake.  To set the path prefix, set
# CMAKE_INSTALL_PREFIX.  To customize where the pieces go beneath that prefix,
# set CMAKE_INSTALL_BINDIR, CMAKE_INSTALL_DATAROOTDIR, CMAKE_INSTALL_SYSCONFDIR,
# or CMAKE_INSTALL_SHAREDSTATEDIR.  Use the INSTALL_GROUP_ID cache variable
# (a string either holding the name or number of the group) as the source for
# the group ID to use for the setgid executable.  Note that with SHARED_INSTALL,
# running "make install" will always require superuser privileges because
# the owner of some of the installed files and directories is set to
# root:${INSTALL_GROUP_ID}.
