CMake is configured by

/usr/bin/cmake --no-warn-unused-cli -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=/usr/bin/c99-gcc -H/path/to/workspace -B/path/to/workspace/build/Debug -G "Unix Makefiles"

It seems that the flag profile-abs-path is available on gcc11, but why am I getting the error?
