#################### Compiler Flags #####################

# -MD    Minimal Rebuild
# -RTC1  Both basic runtime checks
# -MD[d] Multithreaded [debug] DLL
# -Zi    Program Database
# -ZI    Program Database for Edit & Continue
# -WX    General warning Level X
# -wdX   Disable specific warning X
# -wnX   Set warning level of specific warning X to level n

# Overwrite CMake default flags first. Be careful with this
# Only add (not set) the general compiler flags.
# CMake default flags : -DWIN32 -D_WINDOWS -W3 -Zm1000
# additionally for CXX: -EHsc -GR
ADD_COMPILER_FLAGS("-D__WIN32__ -D_WIN32"      CACHE)

# Microsoft unfortunately couldn't integrate a fix issued while VS 2008 beta 2
# was being tested into the final release even though a fix existed...
# And it's actually quite a big issue, you simple can't compile anything.
# Fortunately for us, disabling Minimal Rebuild solves the problem.
REMOVE_COMPILER_FLAGS("-Gm" Debug MSVC09 CACHE)
# And since we have to remove /Gm, let's add /MP2 to speed things up

# "no suitable definition provided for explicit template
# instantiation request" Occurs in VC7 for no justifiable reason.
# ADD_COMPILER_FLAGS("-w44661" CACHE)

# Deprecation warnings when using CRT calls in VC8
# These show up on all C runtime lib code in VC8, disable since they clutter
# the warnings with things we may not be able to do anything about (e.g.
# generated code from nvparse etc). I doubt very much that these calls
# will ever be actually removed from VC anyway, it would break too much code.
