CMAKE_TOOLCHAIN_FILE | |
-------------------- | |
.. versionadded:: 3.21 | |
.. include:: ENV_VAR.txt | |
The ``CMAKE_TOOLCHAIN_FILE`` environment variable specifies a default value | |
for the :variable:`CMAKE_TOOLCHAIN_FILE` variable when there is no explicit | |
configuration given on the first run while creating a new build tree. | |
On later runs in an existing build tree the value persists in the cache | |
as :variable:`CMAKE_TOOLCHAIN_FILE`. |
