+
+  myx_add_external_target(TARGET_NAME
+    [ MODULES_PATH modules_path ] |
+    [ GIT_REPOSITORY url ] |
+    [ GIT_TAG tag ] |
+    [ LOCAL_PATH local_path ] )
+
+Обязательный параметр: `TARGET_NAME` - имя цели, содержащейся во внешнем проекте.
+Параметр `MODULES_PATH` содержит имя каталога, в который будут загружаться
+внешние проекты (по умлолчанию `modules`). Параметр `GIT_REPOSITORY` содержит
+адрес внешнего проекта, который нужно загрузить с помощью git. Параметр `GIT_TAG`
+содержит используемые метку, идентификатор коммита или ветку в репозитории.
+Параметр `LOCAL_PATH` используется для указания пути к подкаталогу, находящемуся
+вне текущего проекта. Его следует указывать только при вызове функции из
+вспомогательного файла `external_targets.cmake`.
