Strange.

I tried to reproduce it here and was not able to.

I added this to the end of a toolchain file, and test.cmake happily issued its 
message without problems:

set(myDir "/home/alex/src/CMake/tc/test.cmake")
include("${myDir}")

If you look into CMakefiles/CMakeSystem.cmake, there the toolchain file is 
included using include(), nothing special there.

Can you send a simple testcase ?
