Summary:                    Cannot escape "#" in add_compile_options
Description: 
I've found no way to escape the "#" character when it needs to occur in an
compiler option in the add_compile_options command. When adding such an option
to, for instance, the CMAKE_CXX_FLAGS variable, it can be escaped with a
backslash ("\"); but this does not appear to work when using
add_compile_options.

Steps to Reproduce: 
For example:

add_compile_options(-Wno-\#pragma-messages)

In the generated output (using the Unix Makefile generator), this string is
added to the command line:

 "-Wno-


Additional Information: 
This is workable; but does not use add_compile_options:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-\\#pragma-messages")
