Summary0015438: project([...] C) for Objective-C
DescriptionThe following cmake scripts has an implicit (working) behavior for Objective-C++:

project(bla CXX)
add_executable(foo foo.c foo.mm)

However the following (equivalent) code does not seems to be working as I would expect:

project(bla C)
add_executable(foo foo.c foo.m)
Steps To Reproduce
Additional InformationWhile Objective-C has never been documented in CMake, it is a required behavior on MacOSX as so many of its API are only accessible through Objective-C.

What works for me is:

cmake_minimum_required(VERSION 3.1)
project(bla C)
add_executable(foo foo.c foo.m)
set_source_files_properties(foo.m PROPERTIES LANGUAGE C)
