[Insight-developers] ITK with free VC++ compiler

[William A. Hoffman]

For now, you will have to do something like this.
Create a file that presets the flags to something different.  
Create a file like this:
(change all the flags to what they need to be,
and save this in a file called InitialCacheVCFreeTools.cmake)

  SET (CMAKE_CXX_FLAGS "/W3 /Zm1000 /GX /GR" CACHE STRING
     "Flags used by the compiler during all build types.")
  SET (CMAKE_CXX_FLAGS_DEBUG "/MDd /Zi /Od /GZ" CACHE STRING
     "Flags used by the compiler during debug builds.")
  SET (CMAKE_CXX_FLAGS_MINSIZEREL "/MD /O1 /D NDEBUG" CACHE STRING
      "Flags used by the compiler during release minsize builds.")
  SET (CMAKE_CXX_FLAGS_RELEASE "/MD /O2 /D NDEBUG" CACHE STRING
     "Flags used by the compiler during release builds (/MD /Ob1 /Oi /Ot /Oy /Gs will produce slightly less optimized but smaller files).")
  SET (CMAKE_CXX_FLAGS_RELWITHDEBINFO "/MD /Zi /O2 /D NDEBUG" CACHE STRING
     "Flags used by the compiler during Release with Debug Info builds.")
  SET (CMAKE_C_FLAGS "/W3 /Zm1000")
  SET (CMAKE_C_FLAGS_DEBUG "/MDd /Zi /Od /GZ" STRING
      "Flags used by the compiler during debug builds.")
  SET (CMAKE_C_FLAGS_MINSIZEREL "/MD /O1 /D NDEBUG" CACHE STRING
      "Flags used by the compiler during release minsize builds.")
  SET (CMAKE_C_FLAGS_RELEASE "/MD /O2 /D NDEBUG" CACHE STRING
     "Flags used by the compiler during release builds (/MD /Ob1 /Oi /Ot /Oy /Gs will produce slightly less optimized but smaller files).")
  SET (CMAKE_C_FLAGS_RELWITHDEBINFO "/MD /Zi /O2 /D NDEBUG" CACHE STRING
     "Flags used by the compiler during Release with Debug Info builds.")


CMakeSetup -C InitialCacheVCFreeTools.cmake

Let me know if this works for you.
I will look into a patch for CMake to support this setup in a cleaner way.
