How to specify source files that shouldn't be compiled in Bazel?

Question

I'm trying to wrap around Poco library. And it contains code like this:

#if defined(POCO_OS_FAMILY_UNIX)
#include "Path_UNIX.cpp"
#elif defined(POCO_OS_FAMILY_WINDOWS) && defined(POCO_WIN32_UTF8)
#if defined(_WIN32_WCE)
#include "Path_WINCE.cpp"
#else
#include "Path_WIN32U.cpp"
#endif
#elif defined(POCO_OS_FAMILY_WINDOWS)
#include "Path_WIN32.cpp"
#endif

But Bazel complains about Path_*.cpp files because I don't mention them in srcs section. What is a proper section to mention these files: they are private, sources, and shouldn't be compiled on their own?

My current workaround is to put them into data section, but it doesn't match conceptually.

Update:

actually data section doesn't work.

You want to use the hdrs attribute. Also if these files are required by dependent libraries you can add it to textual_hdrs .

https://docs.bazel.build/versions/master/be/c-cpp.html#cc_library.textual_hdrs

If you need to hide these files from dependent rules you'll need to use a genrule (or patch command at the repository level) to copy the files to ah extension and modify the source file that includes the files.
