|
Apart from when using the Xcode generator and some Visual Studio generators,
|
|
CMake 3.23 and below will set environment variables like :envvar:`CC`,
|
|
:envvar:`CXX`, etc. when the corresponding language is enabled.
|
|
This only occurs on the very first time CMake is run in a build directory,
|
|
and the environment variables are only defined at configure time, not build
|
|
time. On subsequent CMake runs, these environment variables are not set,
|
|
opening up the opportunity for different behavior between the first and
|
|
subsequent CMake runs. CMake 3.24 and above prefer to not set these
|
|
environment variables when a language is enabled, even on the first run in
|
|
a build directory.
|
|
|
|
The ``OLD`` behavior for this policy sets the relevant environment variable
|
|
on the first run when a language is enabled. The ``NEW`` behavior for this
|
|
policy does not set any such environment variables.
