VLC-QUIC_configure_scripts

For VLC configure to detect QUIC and HTTP3 libraries

Openssl

./config enable-tls1_3 --prefix=/home/devbox/devel/quic_research/build_openssl
make -j$(nproc)
make install_sw

nghttp3

autoreconf -i
./configure --prefix=/home/devbox/devel/quic_research/nghttp3_build --enable-lib-only
make -j$(nproc) 
make install // sudo if needed

ngtcp2

autoreconf -i
./configure PKG_CONFIG_PATH=../build_openssl/lib/pkgconfig:../nghttp3_build/lib/pkgconfig LDFLAGS="-Wl,-rpath,../build_openssl/lib" --prefix=/home/devbox/devel/quic_research
make -j$(nproc)

Finally within VLC:

mkdir build && cd build
PKG_CONFIG_PATH=/home/devbox/devel/quic_research/build_openssl/lib/pkgconfig:/home/devbox/devel/quic_research/nghttp3_build/lib/pkgconfig:/home/devbox/devel/quic_research/ngtcp2/lib ../configure --disable-qt
make -j$(nproc)
make install

For globle installation of the libraries so that it is avaible to use the headers:

Openssl

./config enable-tls1_3
make -j$(nproc)
sudo make install_sw

nghttp3

./configure --enable-lib-only
make -j$(nproc) 
sudo make install

ngtcp2

./configure PKG_CONFIG_PATH=../build_openssl/lib/pkgconfig:../nghttp3_build/lib/pkgconfig LDFLAGS="-Wl,-rpath,../build_openssl/lib"
make -j$(nproc) check
make -j$(nproc)
sudo make install

Finally within VLC:

mkdir build && cd build
./configure (should be enough: Have to test though)
make -j$(nproc)
make install
