What CMake version are you using?

[Czarek]

cmake version 3.7.2
latest stable release

[magreenblatt]

I'm using 3.5.2 and not seeing the warnings. Perhaps the CMake defaults have changed and we need to clear more values like with https://bitbucket.org/chromiumembedded/ ... ake.in-348

[Czarek]

Downgrading to cmake 3.5.2 didn't help. Tried with multiple compilers: VS2008, VS2010, VS2015.

To get rid of the warnings I had to add these two:

set(CMAKE_CXX_FLAGS_RELEASE "")
set(CMAKE_CXX_FLAGS "")

CMAKE_CXX_FLAGS_RELEASE gets rid of the overriding '/MD' with '/MT' warning

CMAKE_CXX_FLAGS gets rid of the /GR /GR- and /W3 /W4 warnings

I had to set both to get rid of all the warnings

Thanks.

Please add a bug.
