variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

Run your build command in an IDF project, not in the ESP-IDF directory

Where is the projects folder ?

There are a bunch of example projects in esp-idf/examples. I suggest you chose one of the projects in get-started.

right got it, thanks

Has anyone found a solution for this yet?

idf.py build always says

[cmake] -- The C compiler identification is unknown
[cmake] -- The CXX compiler identification is unknown
[cmake] -- The ASM compiler identification is unknown

The solution stated above should work, make sure that you are in your the base directory of your project. export ESP-IDF to path by running export.bat in the esp-idf directory, for windows user: then try building your project.
