CMAKE_DEPFILE_FLAGS_<LANG> is not working
If i use set(CMAKE_DEPFILE_FLAGS_C "--dep-file=<DEPFILE>")
in my CMAKE_TOOLCHAIN_FILE
, this option is never appended to the compiler flags and therefore no dependency file is generated. For your information, I'm using cmake 3.15.4, with the ninja generator and a custom compiler, with a toolchain file.
