[CMake] INCLUDE command within a toolchain file is stripping file path if filename is a variable?

Woud you be able to reproduce this "include" error outside of a toolchain scope?
Could you try attached example.

put the two files somewhere and run:
cmake -P includeTest.cmake

by the way which version of CMake are you using?
