So this should not interfere with reducing the overall options. Whatever solution will be applied to all examples should also work for the IR pass examples.

I think he would like to remove LLVM_BUILD_EXAMPLES altogether. That
is, any "cmake" will execute any CMakeLists.txt, "make all" will
always build TutorialSimplyCFG and any execution of `opt` will call

I am in favor of adding (more) tutorials to the repository, joint
trying to point out items to consider.
