| CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT |
| ------------------------------------------- |
| |
| .. versionadded:: 3.7.1 |
| |
| CMake sets this variable to a ``TRUE`` value when the |
| :variable:`CMAKE_INSTALL_PREFIX` has just been initialized to |
| its default value, typically on the first run of CMake within |
| a new build tree. This can be used by project code to change |
| the default without overriding a user-provided value: |
| |
| .. code-block:: cmake |
| |
| if(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT) |
| set(CMAKE_INSTALL_PREFIX "/my/default" CACHE PATH "..." FORCE) |
| endif() |
