### Bootstrapping
Most of Z3's CMake files do not live in their correct location. Instead those
files live in the ``contrib/cmake`` folder and a script is provided that will
copy (or hard link) the files into their correct location.
To copy the files run
```
python contrib/cmake/bootstrap.py create
```
in the root of the repository. Once you have done this you can now build Z3 using CMake.
Make sure you remember to rerun this command if you pull down new code/rebase/change branch so
that the copied CMake files are up to date.
To remove the copied files run
```
python contrib/cmake/bootstrap.py remove
```
Note if you plan to do development on Z3 you should read the developer
notes on bootstrapping in this document.
What follows is a brief walk through of how to build Z3 using some
of the more commonly used CMake generators.

### Boostrapping the CMake build
Z3's CMake system is experimental and not officially supported. Consequently
Z3's developers have decided that they do not want the CMake files in the
``src/`` and ``examples/`` folders. Instead the ``contrib/cmake/bootstrap.py``
script copies or hard links them into the correct locations. For context
on this decision see https://github.com/Z3Prover/z3/pull/461 .
The ``contrib/cmake/bootstrap.py create`` command just copies over files which makes
development harder because you have to copy your modifications over to the
files in ``contrib/cmake`` for your changes to committed to git. If you are on a UNIX like
platform you can create hard links instead by running
```
contrib/cmake/boostrap.py create --hard-link
```
Using hard links means that modifying any of the "copied" files also modifies the
file under version control. Using hard links also means that the file modification time
will appear correct (i.e. the hard-linked "copies" have the same file modification time
as the corresponding file under version control) which means CMake will correctly reconfigure
when invoked. This is why using symbolic links is not an option because the file modification
time of a symbolic link is not the same as the file modification of the file being pointed to.
Unfortunately a downside to using hard links (or just plain copies) is that if
you pull down new code (i.e. ``git pull``) then some of the CMake files under
version control may change but the corresponding hard-linked "copies" will not.
This mean that (regardless of whether or not you use hard links) every time you
pull down new code or change branch or do an interactive rebase you must run
(with or without ``--hard-link``):
```
contrb/cmake/boostrap.py create
```
in order to be sure that the copied CMake files are not out of date.
