What is the actual behavior?

After selecting device type "linux" the warning below is issued in the OUTPUT window.

CMake Warning (dev) at /home/wilsonj/Documents/foldered/espressif/esp-idf/tools/cmake/build.cmake:167 (enable_language): project() should be called prior to this enable_language() call. Call Stack (most recent call first): /home/wilsonj/Documents/foldered/espressif/esp-idf/tools/cmake/build.cmake:244 (__build_set_lang_version) /home/wilsonj/Documents/foldered/espressif/esp-idf/tools/cmake/idf.cmake:55 (__build_init) /home/wilsonj/Documents/foldered/espressif/esp-idf/tools/cmake/project.cmake:29 (include) CMakeLists.txt:11 (include) This warning is for project developers. Use -Wno-dev to suppress it.
The same warning is also issued in the TERMINAL window for the following:

Clearing the build folder and then building issues the warning.

Running ESP-IDF: idf.py reconfigure task issues the warning (but isn't highlighted)

Changing a CMakeLists.txt file causes the error to be reported for the first run, but not subsequent ones.

idf.py clean and idf.py build and idf.py reconfigure from the command line also cause the warning to be issued.

Steps to reproduce.

Hello @i400s ,

thank you for pointing this out. It seems that this warning was introduced in recent cmake versions(>3.29) with https://gitlab.kitware.com/cmake/cmake/-/merge_requests/9396. We will look into this. Thank you!
