#Cmake, multiple toolchains, howto simple switch

[Mário Oravec]

ok Leon, me too, there is only one lunch configurator. You can configure to run 
app or debug app. I do not have sufficiont know-how here to help you. I use 
debuging  rarely, most of the time it is sufficient to run unit tests for me. 
And if to come situation to debug I have just one debug lunch <test> and
do not need to change it.
