not sure if there is a better way to resolve this issue:
declaring .RC files as header-only break ninja builds on non-windows
platforms.
--->8---
cmake currently tries to initialize the language rules for all source
files. when HEADER_FILE_ONLY is used to mark files which should be added
to the generated project, but should not be compiled, this will
nevertheless try to initialize the language, which might fail on that
specific platform. this is a practical issue when declaring .RC files as
header-only on non-windows platforms.
