[CMake] GLOB_RECURSE

[Michael Hennebry]

Emphasis on curse.

from CMakeLists.txt:

file (GLOB_RECURSE ards ./ArduinoCore/src *.cpp *.c)
file (GLOB_RECURSE apps ./SensorUnit *.cpp *.c)

message("apps:;${apps};:apps")
message("ards:;${ards};:ards")

Both lists have ArduinoCore and SensorUnit sources.
They both have precisely 57 entries.
They both have three entries from sb-build.

What is going on?

>From the siblings' parent:
$ ls -F
ArduinoCore/    SensorUnit/              generic-gcc-avr.cmake
CMakeLists.txt  from-build-directory.sh  sb-build/

I tried RELATIVE.
I tried replacing the dot with ${CMAKE_SOURCE_DIR}.
All to no avail.

I'm stumped.
