Linux build make tools fails due to missing mbedtls

[lask]

I am trying to build for Linux and got the following error:

~/toitlang/toit$ make tools

I have set my IDF_PATH variable to the correct path:

~/toitlang/toit$ echo $IDF_PATH 
/home/lau/toitware/esp-idf/

Any idea why it doesn't work?

Found the issue (thanks @floitsch):
I skipped the submodule initialization in this section https://github.com/toitware/toit#how-to-build-toit-for-esp32

pushd $IDF_PATH
git submodule update --init --recursive
popd

After updating the submodules in the esp-idf directory, I did a make clean in the toitlang directory.
