Description Brad Davis 2014-01-17 08:06:27 UTC 
On windows environments, in order to avoid having to deal with providing the Microsoft C runtime re-distributable, it's often desirable to be able to configure your code to use the static C runtime (use /MT and /MTd instead of /MD and /MDd).  This allows the developer to create a single executable that has no DLL dependencies.  


CMake doesn't appear to support this as a simple toggle, but there is some information out there on how to trigger this by manipulating the compiler flags (see http://stackoverflow.com/questions/10113017/setting-the-msvc-runtime-in-cmake ) and a number of other projects support this, notably OpenCV, which has it's own CMAKE setting flag for this (BUILD_WITH_STATIC_CRT) and encapsulates the logic required to accomplish it in this file:  https://github.com/Itseez/opencv/blob/master/cmake/OpenCVCRTLinkage.cmake
