[llvm-dev] cmake: program name prefix?

[Neil Henning via llvm-dev]

At a guess if you really wanna do this, you could have a parent 
CMakeLists.txt which would include the LLVM CMakeLists.txt, and in the 
parent one you'd want to override add_executable (like in this example 
https://cmake.org/pipermail/cmake/2011-March/043320.html) to change the 
name of the executable target. Your best to do set_target_properties 
with OUTPUT_NAME to do that.

No idea if this works, but I've done similar horrific things in CMake 
before and they tend to work.

Best of luck,

-Neil.
