Exactly. That's why Eclipse needs details about the
toolchain itself. I only see these two ways: 
1) specify everything in the toolchain file ->
cmake will know the paths -> compile_commands.json -> eclipse
2) Eclipse knows the toolchains -> tells cmake
which one to use / generate toolchain file

Having more than one gcc in PATH leads to a mess.
