Building ASSIMP with MinGW causes file too big error

I am building ASSIMP using cmake and mingw-w64 on windows 10 and it gives me "file too big" errors while creating the object code. I tried using MinGW and MinGW-w64 and both give me the same error. I am using the default settings, I configure the project with cmake, generate the makefile and then run mingw32-make. Is there some kind of flag I can set to fix this?

Compiler:

g++ (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0

Here is the output: 

[ 59%] Building CXX object code/CMakeFiles/assimp.dir/Importer/StepFile/StepFileImporter.cpp.obj

EDIT: I was using the master branch of Assimp from github, which has newer experimental features. I downloaded an older release version and I did not get the same errors.

What worked for me :
Go into the CMakeLists.txt and add:

set(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} "-O3")

Then compile with some options off:

cmake .. -G "Unix Makefiles" -DASSIMP_BUILD_ASSIMP_TOOLS=OFF -DASSIMP_BUILD_TESTS=OFF
make -j4 && make install

It worked for 5.0.0-rc1 and 5.0.1 too.
