Compiler fail when I set WITH_BORINGSSL=1 and WITH_IO_URING=1 make

Reproduce the combined build with WITH_BORINGSSL=1 WITH_IO_URING=1, then compare it with the two successful single-option builds. Inspect src/crypto/openssl.c and src/io_uring/io_loop.c, focusing on the incomplete-type errors and pointer warnings. Done means the combined command compiles without those errors and warnings.

I have installed the libraries:

apt-get install libasio-dev libfmt-dev libuv1-dev zlib1g-dev libssl-dev liburing-dev

I have downloaded the last version with:

git clone --recursive https://github.com/uNetworking/uWebSockets

I have build uSockets/boringssl with CMAKE

mkdir build
cd build
cmake ..
make

cd /uWebSockets

So, if I set only "WITH_BORINGSSL=1 make", it compiles without problems.

If I set only "WITH_IO_URING=1 make", it also compiles without problems.

But if I set them together like "WITH_BORINGSSL=1 WITH_IO_URING=1 make", I get the following compilation errors:
