<pre>Source/cmake/OptionsWin.cmake has a following trick to force using /MT.
<span class="quote">> foreach (flag_var
> CMAKE_CXX_FLAGS CMAKE_CXX_FLAGS_DEBUG CMAKE_CXX_FLAGS_RELEASE
> CMAKE_CXX_FLAGS_MINSIZEREL CMAKE_CXX_FLAGS_RELWITHDEBINFO)
> # Use the multithreaded static runtime library instead of the default DLL runtime.
> string(REGEX REPLACE "/MD" "/MT" ${flag_var} "${${flag_var}}")</span >
>
<span class="quote">> # No debug runtime, even in debug builds.
> if (NOT DEBUG_SUFFIX)
> string(REGEX REPLACE "/MTd" "/MT" ${flag_var} "${${flag_var}}")
> string(REGEX REPLACE "/D_DEBUG" "" ${flag_var} "${${flag_var}}")
> endif ()
> endforeach ()</span >
But, this trick affect only to C++, but C.
As the result, WebKitGUID.lib is build with debug CRT because it has C source files.
The below warning messages are reported by this issue.
<span class="quote">> LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library</span ></pre>
