/bigobj is flag required to compile the CLAP target with MSVC

[giohappy]

The CLAP target requires the /bigobj flag to compile with MSVC.
I set it manually inside CMakeLists.txt:

if(MSVC)
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /bigobj")
endif()

I'm building with VS 2022 on Windows 11 x86 64.

@cesaref I suppose this can be closed since it's been fixed in 2c9e299
