Subject: [PATCH] Fix codegen configure_file writing config.h into source tree

codegen/CMakeLists.txt generates config.h directly into the source
tree (include/ck/config.h) instead of the build directory. This
pollutes the source tree with a build artifact that lacks the #ifndef
guards present in config.h.in, causing -Wmacro-redefined warnings
when macros are also defined via -D flags on the command line.

Write the generated config.h to CMAKE_CURRENT_BINARY_DIR instead,
matching what the main CMakeLists.txt already does (line 530).
