How to set up IDE for cross-building?

[jasper77]

I'd like to set up CodeLite to use for an embedded software project where the target uses a different toolchain, including a different compiler, linker, and assembler. (It's for the ARM STM32 and there is no OS). I see in CodeLite where I can add a new compiler (Settings / Build Settings / Compilers / "Create New Compiler"), so far so good. However, I also need to set it up to use a different linker and assembler, with associated flags for each. Can I do that in CodeLite, or must I hand write a makefile and set up the project to use that external makefile?
