+# static.cmake -- change flags to link with static runtime libraries

+#

+# Even when BUILD_SHARED_LIBS is OFF, CMake specifies linking wtih

+# multithread DLL, so you give inconsistent linking instructions

+# resulting in warning messages from MS Visual Studio. If you want

+# a static binary, I've found this approach works to eliminate

+# warnings and make everything static:

+#

+# Changes /MD (multithread DLL) to /MT (multithread static)
