# This file sets the basic flags for the C language in CMake.

# if it exists.

# specific file, which is mainly useful for crosscompiling and embedded systems.
# some compilers use different extensions (e.g. sdcc uses .rel)
# so set the extension here first so it can be overridden by the compiler specific file
