Why does this CMake project not set the appropriate MSVC runtime?

Question

I'm trying to understand why the libmysql CMake project configured with /MD and /MDd flags does not generate the appropriate Visual Studio 10 project files. The appropriate CMAKE_ macros have been configured, as shown:

macros

Yet the generated projects are still showing unexpected Runtime Library settings:

Is the CMake GUI for some reason unreliable, or is it possible that another option is overriding the CRT settings?

Was it helpful?

Solution

I found that the cmake project for libmysql has an OS-specific cmake file for Windows which forces static runtimes to be used when generating the Visual Studio solution:

 75   # Force static runtime libraries
 83   FOREACH(flag
 84    CMAKE_C_FLAGS_RELEASE CMAKE_C_FLAGS_RELWITHDEBINFO
 85    CMAKE_C_FLAGS_DEBUG CMAKE_C_FLAGS_DEBUG_INIT
 86    CMAKE_CXX_FLAGS_RELEASE  CMAKE_CXX_FLAGS_RELWITHDEBINFO
 87    CMAKE_CXX_FLAGS_DEBUG  CMAKE_CXX_FLAGS_DEBUG_INIT)
 88    STRING(REPLACE "/MD"  "/MT" "${flag}" "${${flag}}")
 89    SET("${flag}" "${${flag}} /EHsc")
 98   ENDFOREACH()
