 :zap: **These installation instructions are outdated and require a
 refresh**. Nowadays kturtle uses `CMake` as its build system, whereas
 the instructions on the doc refer to the old `autotools` build system.
 
 ## Basic Installation
 
    These are generic installation instructions to install kturtle from
 source. They are intended for developers only, as most users will want
 to install it from the packages available for their OS.
 
    The `configure` shell script attempts to guess correct values for
 various system-dependent variables used during compilation.  It uses
 those values to create a `Makefile` in each directory of the package.
 It may also create one or more `.h` files containing system-dependent
 definitions.  Finally, it creates a shell script `config.status` that
 you can run in the future to recreate the current configuration, a file
 `config.cache` that saves the results of its tests to speed up
 reconfiguring, and a file `config.log` containing compiler output
 (useful mainly for debugging `configure`).
 
    If you need to do unusual things to compile the package, please try
 to figure out how `configure` could check whether to do them, and mail
 diffs or instructions to the address given in the `README` so they can
 be considered for the next release.  If at some point `config.cache`
 contains results you don`t want to keep, you may remove or edit it.
 
    The file `configure.in` is used to create `configure` by a program
 called `autoconf`.  You only need `configure.in` if you want to change
 it or regenerate `configure` using a newer version of `autoconf`.
 
 The simplest way to compile this package is:
 
   1. `cd` to the directory containing the package`s source code and type
      `./configure` to configure the package for your system.  If you`re
      using `csh` on an old version of System V, you might need to type
      `sh ./configure` instead to prevent `csh` from trying to execute
      `configure` itself.
 
      Running `configure` takes a while.  While running, it prints some
      messages telling which features it is checking for.
 
   2. Type `make` to compile the package.
 
   3. Type `make install` to install the programs and any data files and
      documentation.
 
   4. You can remove the program binaries and object files from the
      source code directory by typing `make clean`.  
 
 ## Compilers and Options
 
    Some systems require unusual options for compilation or linking that
 the `configure` script does not know about.  You can give `configure`
 initial values for variables by setting them in the environment.  Using
 a Bourne-compatible shell, you can do that on the command line like
 this:
 
      CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
 
 Or on systems that have the `env` program, you can do it like this:
      env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
 
 ## Compiling For Multiple Architectures
 
    You can compile the package for more than one kind of computer at the
 same time, by placing the object files for each architecture in their
 own directory.  To do this, you must use a version of `make` that
 supports the `VPATH` variable, such as GNU `make`.  `cd` to the
 directory where you want the object files and executables to go and run
 the `configure` script.  `configure` automatically checks for the
 source code in the directory that `configure` is in and in `..`.
 
    If you have to use a `make` that does not supports the `VPATH`
 variable, you have to compile the package for one architecture at a time
 in the source code directory.  After you have installed the package for
 one architecture, use `make distclean` before reconfiguring for another
 architecture.
 
 ## Installation Names
 
    By default, `make install` will install the package`s files in
 `/usr/local/bin`, `/usr/local/man`, etc.  You can specify an
 installation prefix other than `/usr/local` by giving `configure` the
 option `--prefix=PATH`.
 
    You can specify separate installation prefixes for
 architecture-specific files and architecture-independent files.  If you
 give `configure` the option `--exec-prefix=PATH`, the package will use
 PATH as the prefix for installing programs and libraries.
 Documentation and other data files will still use the regular prefix.
 
    If the package supports it, you can cause programs to be installed
 with an extra prefix or suffix on their names by giving `configure` the
 option `--program-prefix=PREFIX` or `--program-suffix=SUFFIX`.
 
 ## Optional Features
 
    Some packages pay attention to `--enable-FEATURE` options to
 `configure`, where FEATURE indicates an optional part of the package.
 They may also pay attention to `--with-PACKAGE` options, where PACKAGE
 is something like `gnu-as` or `x` (for the X Window System).  The
 `README` should mention any `--enable-` and `--with-` options that the
 package recognizes.
 
    For packages that use the X Window System, `configure` can usually
 find the X include and library files automatically, but if it doesn`t,
 you can use the `configure` options `--x-includes=DIR` and
 `--x-libraries=DIR` to specify their locations.
 
 ## Specifying the System Type
 
    There may be some features `configure` can not figure out
 automatically, but needs to determine by the type of host the package
 will run on.  Usually `configure` can figure that out, but if it prints
 a message saying it can not guess the host type, give it the
 `--host=TYPE` option.  TYPE can either be a short name for the system
 type, such as `sun4`, or a canonical name with three fields:
 
      CPU-COMPANY-SYSTEM
 
 See the file `config.sub` for the possible values of each field.  If
 `config.sub` isn`t included in this package, then this package doesn`t
 need to know the host type.
 
    If you are building compiler tools for cross-compiling, you can also
 use the `--target=TYPE` option to select the type of system they will
 produce code for and the `--build=TYPE` option to select the type of
 system on which you are compiling the package.
 
 ## Sharing Defaults
 
    If you want to set default values for `configure` scripts to share,
 you can create a site shell script called `config.site` that gives
 default values for variables like `CC`, `cache_file`, and `prefix`.
 `configure` looks for `PREFIX/share/config.site` if it exists, then
 `PREFIX/etc/config.site` if it exists.  Or, you can set the
 `CONFIG_SITE` environment variable to the location of the site script.
 A warning: not all `configure` scripts look for a site script.
 
 ## Operation Controls
 
    `configure` recognizes the following options to control how it
 operates.
 
 `--cache-file=FILE`
      Use and save the results of the tests in FILE instead of
      `./config.cache`.  Set FILE to `/dev/null` to disable caching, for
      debugging `configure`.
 
 `--help`
      Print a summary of the options to `configure`, and exit.
 
 `--quiet`
 `--silent`
 `-q`
      Do not print messages saying which checks are being made.
 
 `--srcdir=DIR`
      Look for the package`s source code in directory DIR.  Usually
      `configure` can determine that directory automatically.
 
 `--version`
      Print the version of Autoconf used to generate the `configure`
      script, and exit.
 
 `configure` also accepts some other, not widely useful, options.
