Thanks a ton, @Microcontroller. That did it! (And thanks for looking @ESP_Sprite.)

I am having a problem moving components outside of a project folder. With the following directory structure...

C:\ESP\sprinkle
└─sprinkle-sensor
├─CMakeLists.txt
├─sdkconfig
├─build
├─components
│ └─sprinkle_common
│ ├─CMakeLists.txt
│ ├─component.mk
│ ├─sprinkle_common.c
│ └─include ...
