Move them a directory above.
Makes them more visible, they don't need to be in /addons.

 If no add-on definitions could be found, the buildsystem assumes that the bootstrapping of the add-on definition repositories hasn't been performed yet and automatically executes the add-on bootstrapping buildsystem located in the *bootstrap* sub-directory with the default settings (i.e. *all* add-ons from all pre-defined add-on definition repositories are bootstrapped into the directory pointed to by the *ADDONS_DEFINITION_DIR* option).
 
 ## Buildsystem variables

+The buildsystem uses the following addon-related variables (which can be passed into it when executing cmake with the -D`<variable-name>=<value>` format) to manipulate the build process:
 - `ADDONS_TO_BUILD` has two variations, which are tested in order:
      - a quoted, space delimited list of `<addon-id>s` that you want to build (default is *all*)
      - a regular expression that every `<addon-id>` is matched against (e.g. `ADDONS_TO_BUILD="pvr.*"`) to build all pvr add-ons
 - `ADDONS_DEFINITION_DIR` points to the directory containing the definitions for the addons to be built
 - `ADDON_SRC_PREFIX` can be used to override the add-on repository location. It must point to the locally available parent directory of the add-on(s) to build. `<addon-id>` will be appended to this path automatically
-- `CMAKE_BUILD_TYPE` specifies the type of the build. This can be either *Debug* or *Release* (default is *Release*)
 - `CMAKE_INSTALL_PREFIX` points to the directory where the built add-ons and their additional files (addon.xml, resources, ...) will be installed to (defaults to `<ADDON_DEPENDS_PATH>`)
-- `CMAKE_TOOLCHAIN_FILE` can be used to pass a toolchain file into the add-on builds
 - `ADDON_DEPENDS_PATH` points to the directory containing the *include* and *lib* directories of the add-ons' dependencies.
 - `CORE_SOURCE_DIR` points to the root directory of the project (default is the absolute representation of ../../.. starting from this directory)
 - `BUILD_DIR` points to the directory where the add-ons and their dependencies will be downloaded and built
 - `PACKAGE_ZIP=ON` means that the add-ons will be 'packaged' into a common folder, rather than being placed in `<CMAKE_INSTALL_PREFIX>/lib/kodi/addons` and `<CMAKE_INSTALL_PREFIX>/share/kodi/addons`
 - `PACKAGE_DIR` points to the directory where the ZIP archived add-ons will be stored after they have been packaged (defaults to `<BUILD_DIR>/zips`)
-- `ARCH_DEFINES` specifies the platform-specific C/C++ preprocessor defines (defaults to empty)
 - `ADDON_TARBALL_CACHING` specifies whether downloaded add-on source tarballs should be cached or not (defaults to *ON*)

 ## Building
 The buildsystem makes some assumptions about the environment which must be met by whoever uses it:
-- Any dependencies of the add-ons must already be built and their include and library files must be present in the path pointed to by `<CMAKE_PREFIX_PATH>` (in *include* and *lib* sub-directories)
-
-To trigger the cmake-based buildsystem the following command must be executed with `<path>` set to this directory (absolute or relative) allowing for in-source and out-of-source builds
-
-`cmake <path> -G <generator>`
-
-CMake supports multiple generators. See [here] (https://cmake.org/cmake/help/v3.1/manual/cmake-generators.7.html) for a list.

-In case of additional options the call might look like this:
-
-cmake `<path>` [-G `<generator>`] \  
-      -DCMAKE_BUILD_TYPE=Release \  
-      -DCORE_SOURCE_DIR="`<path-to-app-root>`" \  
-      -DARCH_DEFINES="-DTARGET_LINUX" \  
-      -DADDON_DEPENDS_PATH=`<path-to-built-depends>` \  
-      -DCMAKE_INSTALL_PREFIX="`<path-to-install-directory`"
