The README's Linux test build has never worked: both the bridge and the
test executable carry INSTALL_RPATH "$ORIGIN" and expect libmsquic.so.2
beside them, but only scripts/build-quic-native.sh's packaged output
directory ever got that copy. A test build produced a binary that died
at once with "cannot open shared object file". Fix it where the
knowledge already lives instead of adding a README workaround: CMake
already receives MSQUIC_LIB_DIR, so the test target now copies
libmsquic.so.2 beside itself in a POST_BUILD step.
While verifying the README's own worked example end to end, found a
second, independent break in the same docker block: MSQUIC_INCLUDE_DIR
and MSQUIC_LIB_DIR were passed as paths relative to the repository
root, but CMake resolves a relative cache-variable path against the
CMakeLists.txt that consumes it, not the invocation directory, so the
compile failed on a missing msquic.h before it ever reached the
loader. Made both paths absolute with $(pwd) and documented why.
