### Fix annoying warnings about CMAKE_TOOLCHAIN_FILE

Hello, I am building some components on Ubuntu 12.04 LTS, with ROS fuerte, rtt build from source from latest master (e95fe17c5ef504b03785818260d212d54e5bdf54). I am building components with rosmake, and sometimes I get the following annoying warning during build:

CMake Warning:
Manually-specified variables were not used by the project:

CMAKE_TOOLCHAIN_FILE


I ran rgrep, and verified that none of our CMakeLists are defining this variable. It does appear in the CMakeCache files, which I assume is what is throwing the warning.

Should I silence these warnings, and how?
