Compilation error on Windows with MinGW

[mustafa-gokce]

I am trying to build the project (1.3.0-latest) under the Windows with MinGW (C++ 17).
It throws error such as CMake not found an option "-z" and also compilation error as "undefined reference to `__stack_chk_fail'" on many source files.
For a workaround I am patching

oatpp/cmake/compiler-flags.cmake

Line 265 in 14ca5e5

add_compiler_flags(4.6 "-Wl,-z,defs")

through

oatpp/cmake/compiler-flags.cmake

Line 267 in 14ca5e5

add_compiler_flags(4.6 "-Wl,-z,relro")

by commenting those lines out and also commenting the line

oatpp/cmake/compiler-flags.cmake

Line 253 in 14ca5e5

add_compiler_flags(4.6 "-fstack-protector-strong")

to get rid of undefined reference errors.
The project compiles fine with this but I am not sure it is a good idea to remove those lines.
Just for the heads up...

EDIT-1,
It may be relevant that I'm including the oatpp to my project like:

# add dependency library to project library
add_subdirectory(dep/oatpp)
target_link_libraries(${project_name}-lib oatpp)

EDIT-2,
I am experiencing some issues with build types too.
It seems like building in debug mode and release mode outputs similar binary size on executable around 30-40MB (on 1.3.0-latest) which I was building the project in release mode around 1-2MB (on 1.3.0).
Root cause is lines:

oatpp/cmake/compiler-flags.cmake

Line 116 in 14ca5e5

add_compiler_flags(4.6 "-g3")

and

oatpp/cmake/compiler-flags.cmake

Line 120 in 14ca5e5

add_compiler_flags(10 "-g3")
