Summary:                    /EHs-c- or /EHs- /EHc- as COMPILE_FLAGS target
property does not remove /EHsc from the global CMAKE_CXX_FLAGS
Description: 
Sometimes when adding external projects replacing /EHsc with /EHs-c- to disable
exceptions on CMAKE_CXX_FLAGS is not an option because it may break the external
project, but when adding /EHs-c- or /EHs- /EHc- to the COMPILE_FLAGS property of
the local project, the /EHsc flag remains, causing compiler command line
warnings:

cl : Command line warning D9025: overriding '/EHs' with '/EHs-'
cl : Command line warning D9025: overriding '/EHc' with '/EHc-'

This does not seem to happen when /GR- is set, in that case the global flag from
CMAKE_CXX_FLAGS seems to vanish.

Steps to Reproduce: 
add_executable( test test.cpp )
set_target_properties(test PROPERTIES COMPILE_FLAGS "/EHs-c- /D_HAS_EXCEPTIONS=0
/GR-")
