How do I enable the SSE/SSE2 instruction set in Visual Studio 2008 (using CMake)?

In Visual Studio 2005 I went in:

View --> Property Pages --> C/C++ --> Code Generation --> Enable Enhanced Instruction Set

But in Visual Studio 2008?

Thanks in advance

If you are using inline assembler __asm { .... } you don't need to enable it.

But if you enable SSE you have to be careful. It may be that the code is slower than normal FPU code.

Using CMake you could add the following to CMakeLists.txt:

IF(MSVC)
   ADD_DEFINITIONS(/arch:SSE)
ENDIF(MSVC)

or /arch:SSE2.

If you're looking for SSE/SSE2: Project > Properties > Configuration Properties > C/C++ > Code Generation > Enable Enhanced Instruction Set, or append /arch:SSE (or /arch:SSE2) in Command Line > Additional Options.

You need to have a native project, and at least one .cpp file added to access this, though.
