+At the time of writing, there are 3 main ways in CMake to create non-internal

+command-line option, through CMake presets, or similar:
 * `option()`
 * `set(<variable> <value> CACHE <type> <docstring>)`
 * `cmake_dependent_option()`

 ```cmake
 php_set(

-It sets the given CACHE `<variable>` of `<type>` to a `<value>` if `<condition>`
-is met. Otherwise it sets the `<variable>` to `<default>` value and hides it in
-the GUI.
+It sets a CACHE `<variable>` of `<type>` to a `<value>`.
 
-* The `CACHE` `<type>` can be `BOOL`, `FILEPATH`, `PATH`, or `STRING`.
+* `TYPE` can be `BOOL`, `FILEPATH`, `PATH`, or `STRING`.
 
-* `STRINGS` is an optional list of items when `CACHE` `STRING` is used to create
-  a list of supported options to pick in the GUI.
+* `CHOICES` is an optional list of items when `STRING` type is used to create
+  a list of supported options to pick in the GUI. Under the hood, it sets the
+  `STRINGS` CACHE variable property.
 
-* `DOC` is a short variable help text visible in the GUIs. Multiple strings are
-  joined together.
+* `VALUE` is the default variable value. There are two ways to set default
+  value.
+
+  * When using the `IF <condition>` argument, it sets the variable to `<value>`
+    if `<condition>` is met. Otherwise it sets the `<variable>` to `ELSE_VALUE`
+    `<default>` and hides it in the GUI, if `ELSE_VALUE` is given. Under the
+    hood `ELSE_VALUE` will set `INTERNAL` cache variable if `<condition>` is not
+    met. If `ELSE_VALUE` is not provided, the `INTERNAL` cache variable is not
+    set (it is undefined).
+
+    `IF` behaves the same as the `<depends>` argument in the
+    `cmake_dependent_option()`. This supports both full condition sytanx and
+    semicolon-separated list of conditions.
+
+  * When using only `VALUE` signature, it sets the cache variable to `<value>`.

-* `IF` behaves the same as the `<depends>` argument in
