Building from Source
---------------------
If you are not installing slsdet binaries from conda, but instead building from
source, please refer to :ref:`the installation section<Installation>` for details.
Don't forget to compile with the option SLS_USE_PYTHON=ON to enable the Python
bindings or if you use the cmk.sh script -p.
.. note ::
Ensure that the python lib compiled is for the expected python version.

For example, build/bin/_slsdet.cpython-39-x86_64-linux-gnu.so for Python v3.9.x
