from `include_directories("${CMAKE_CURRENT_BINARY_DIR}")`

I was debugging why no directory I specify in `target_include_directories` allow me to access the header after `generate_export_header`, even when explicitly specifying `EXPORT_FILE_NAME` and using angle brackets (with different path relativity).

One thing I finally tried was to output to `${CMAKE_CURRENT_BINARY_DIR}/${LIBRARY_NAME}_export.h` and adding that directory to the global search with `include_directories`. That’s when this error occurred. I’m assuming the error should be a different one (if an error at all).

What is the absolute path to your binary directory? Do you have `[` or `]` in the path anywhere?

No spaces and no `[` or `]` in the path. Windows. Short path.

I had same problem. In my case absolute path contained non-ascii caharacters.
