For my CPack configuration, I have a step where I do -  
`set(CPACK_INSTALL_SCRIPTS ${CMAKE_SOURCE_DIR}/cmake/CPackfoo.cmake)`

Inside `CPackfoo.cmake` , I am using a command - `execute_process(COMMAND textutil -convert html README.md -output "${CMAKE_BINARY_DIR}/README.html")`  
But it seems like `${CMAKE_BINARY_DIR}` is not recognized here and `textutil` tries to write `README.html` to `/` . Is there an obvious way to fix this that I am missing?

I think that sounds right. Not all CMake variables are transported over to CPack time. Apparently `CMAKE_BINARY_DIR` is one of them. You could `configure_file(@ONLY)` the script and use `@CMAKE_BINARY_DIR@` to have it be replaced at a time when it is known.
