On at least MSVC 14.50.35717, EE builds can fail with an error
while compiling tweak.cpp:
fatal error C1128: number of sections exceeded object file
format limit: compile with /bigobj
This commit adds a section to CMakeLists.txt to compile tweak.cpp
with this flag when using MSVC.
MSVC's default limit is 65,279 (~16-bit unsigned integer) of COFF
sections per .obj file, and the number of templates instantiating
sections in this file is near or at that limit.
The /bigobj flag raises the COFF section limit to about 4 billion
(32-bit unsigned integer). Alternatives would be to either split
tweak.cpp into per-component units or enable /bigobj across the
project in MSVC.
GCC and MinGW don't limit COFF sections, so they aren't affected.
