Linux build issue: missing directory .~/esp/esp-idf/components/freertos/include

[TRIA]

Building from command line on Linux 20.04, latest IDF, latest dev branch, I get this failure:
'/home/srb/esp/esp-idf/components/freertos/include/freertos' is not a directory.

Here's where it's looking for the include dir in:

srb@sdr2:~/esp/esp-idf/components/freertos$ ls
CMakeLists.txt  FreeRTOS-Kernel      FreeRTOS-openocd.c  linker.lf         test
esp_additions   FreeRTOS-Kernel-SMP  Kconfig             sdkconfig.rename
srb@sdr2:~/esp/esp-idf/components/freertos$ 

There's no include dir. The following is the (majority of) the cmake output:

srb@sdr2:~/rinasense/build$ cmake ..

Skipping the download of /home/srb/.espressif/espidf.constraints.v5.0.txt because it was downloaded recently. If you believe that this is causing you trouble then remove it manually and re-run your install script.
