CMAKE_TOOLCHAIN_FILE

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`.
