I think you are missing a colon after the first ">". I just tried a command
like the following and it produces the right compiler command line options
for me (on macOS using CMake 3.11.0 with either Ninja or Xcode):
target_compile_options(someTarget PRIVATE
$<$<COMPILE_LANGUAGE:CXX>:-Wall;-Wextra>
)
I also works for me even without the semi-colon (i.e. using a space
instead), which was kinda surprising given that I didn't quote the whole
generator expression. Not sure about other platforms or generators.
