The CMAKE_C_COMPILER: xtensa-esp32-elf-gcc is not a full path and was not found in the PATH.

A just created ESP32 C project show the following errors in CMake tab:

...

The Crosscompiler Path is specified on ESP32 config settings tab as /Users/xxx/.espressif/tools/xtensa-esp32-elf/esp-2020r2-8.2.0/xtensa-esp32-elf/bin (it has xtensia-esp32-elf-gcc file inside of). So, looks like ESP32 plugin don't pass this path to CMake correctly.

For me the issue was solved by removing the environment variables the plugin set's on cmake config in the settings and calling export.bat in the esp-idf folder.
