I do the same things, but I configure C files to .CPP files, but just
have a directory structure in the CMAKE_BINARY_DIR to put them... most
compile systems don't care if it's in a specific location, and cmake
will end up referencing it by full pathname where it was.  But... so
you can probably continue to use that temporary dir, and if another
build system doesn't use it, it'll still be there....
