-- lmdb
 - CMake 3.4 or higher
 - qxmpp 1.1.0 or higher

 Here is the list of keys you can pass to configuration phase of `cmake ..`. 
 - `CMAKE_BUILD_TYPE` - `Debug` just builds showing all warnings, `Release` builds with no warnings and applies optimizations (default is `Debug`)
 - `SYSTEM_QXMPP` - `True` tries to link against `qxmpp` installed in the system, `False` builds bundled `qxmpp` library (default is `True`)
+- `SYSTEM_LMDBAL` - `True` tries to link against `LMDABL` installed in the system, `False` builds bundled `LMDBAL` library (default is `True`)
 - `WITH_KWALLET` - `True` builds the `KWallet` capability module if `KWallet` is installed and if not goes to `False`. `False` disables `KWallet` support (default is `True`)
 - `WITH_KIO` - `True` builds the `KIO` capability module if `KIO` is installed and if not goes to `False`. `False` disables `KIO` support (default is `True`)
 - `WITH_KCONFIG` - `True` builds the `KConfig` and `KConfigWidgets` capability module if such packages are installed and if not goes to `False`. `False` disables `KConfig` and `KConfigWidgets` support (default is `True`)
+- `WITH_OMEMO` - `True` builds the OMEMO encryption, requires `qxmpp` of version >= 1.5.0 built with OMEMO support. `False` disables OMEMO support (default is `True`)
