CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT | |
------------------------------------------- | |
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() |
