Setup QtCreator with cross compiling cmake project

[cmanea]

Hi,

I'm using QtCreator 4.0.1 and I'm trying to cross compile a qt cmake project, but it fails like this at ./cmake stage:
Full cmake log can be seen in the attached cmake.txt file.

-- Disabled building system-sync projects
-- Enabled building the trip logger project
-- Enabled building the Front-End SDK
-- Enabled building the tests

You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:

I attached the setup of the kit!


So my issue is that after the cmake configuration is finished, qt creator comes up with the cache issue and runs again cmake with other env variables:

I'm using a toolchain file for cross compiling and passing it to qtcreator in the CMake Configuration like this: "CMAKE_TOOLCHAIN_FILE:STRING=~/toolchain.cmake".
I have only the "CMAKE_TOOLCHAIN_FILE" in my "CMake Configuration."
