To Reproduce
Using Windows MSYS2 MINGW64 as administrator.
liboqs is built like this:

# mkdir build && cd build
# cmake -GNinja -DCMAKE_INSTALL_PREFIX=/d/Project/liboqs-compiled -DBUILD_SHARED_LIBS=ON -DOQS_USE_OPENSSL=OFF -DCMAKE_BUILD_TYPE=Release -DOQS_BUILD_ONLY_LIB=ON -DOQS_DIST_BUILD=ON ..
# ninja
# ninja install

oqs-provider is built like this:

 mkdir build && cd build
 cmake -GNinja -DCMAKE_PREFIX_PATH="D:\Project\install" -DOPENSSL_ROOT_DIR="D:\Project\openssl-3.2.1" -Dliboqs_DIR="D:\Project\liboqs-compiled\lib\cmake\liboqs" -S ..
cmake --build .

Environment (please complete the following information):

• OS: Windows 11
• OpenSSL version: OpenSSL 3.2.1 30 Jan 2024 (Library: OpenSSL 3.2.1 30 Jan 2024)
• oqsprovider version: git checkout d540c28

I figured it out that mkdir() function that is specified in io.h just takes one argument, so simply change to if(mkdir(certsdir)) as mention in this stackoverflow.

This will successfully build the oqsprovider, but the size of .dll file is significantly small (625kb) and openssl doesn't recognize it even when I have edit the openssl.cnf file

Thanks @HarryLee02 for the report. Unfortunately, I'm not exactly a "Windows connoisseur" -- would you be willing to do a PR? Or is there another (looks unrelated) problem with

but the size of .dll file is significantly small (625kb)

So are there symbols un-resolved in the resultant .dll?
