[CMake] toolchain file and initial cache

[Tom Deblauwe]

Hello,

I have a question: Using the -C option you can specify an initial cache 
file. I have this case where I like to specify some initial cache 
values, but also a toolchain file. Can I combine this and add a line in 
the initial cache file:

set(CMAKE_TOOLCHAIN_FILE "toolchain.cmake" CACHE PATH "Toolchain file")

Will this work the same?
Best regards,
Tom
