[CMake] Question about searching for another toolchain

[Workbench@gmx.at]

Hello everyone,

i'm realtively new to CMake and i find it awesome, the best building 
system ever !


Now to my question: I want to support either intel or amd specific 
functions in my application, that means i need either the amd or the 
intel sdk, i know how i can set another toolchain and stuff but how can 
i search for the different sdk's because the use have to install them 
and i don't know where.


how can i make cmake find the toolchain i'm searching for ?


best regards!
