`RegularExpression::compile(): Invalid range in [].`

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.
