Compile with clang instead of gcc

Question

I have downloaded openssh-6.4p1 for Linux and I want to compile it using clang instead of gcc . How can I tell the compilation engine to do this? Do I need to modify configure ?

Answer 1

You can try to use the option command like this:

option(USE_CLANG "build application with clang" ON) # OFF is the default

and then you can wrap the clang-compiler settings in the if() condition like this:

if(USE_CLANG)
    SET (...)
    //...
endif(USE_CLANG)
