This works for me:

project(asm CXX)
add_executable(foo foo.bar)
set_source_files_properties(foo.bar PROPERTIES LANGUAGE CXX)

Re: [CMake] nonstandard C++ source filename extension
Hi Dave.
This looks like a message directly from your compiler. Does it work if you
try to compile the file manually (no CMake)?
