# Builds open62541 and QtOpcUa from submodules automatically on first
# configure. Subsequent configures skip the dep builds (delete
# build/deps/*-install/ to force a rebuild).

# Prerequisites: Qt 6.10.2+ with qt-cmake in PATH, OpenSSL dev headers,
# Ninja, and initialized submodules:
#   git submodule update --init --recursive

# ── Runtime quirks ──────────────────────────────────────────────────────────
# BobinkQtOpcUa builds open62541 as a shared library. The QtOpcUa backend
# plugin (loaded at runtime via dlopen) needs to find it. These two lines
# make that work during development:

# 1. RPATH: embed the dep lib dirs so the dynamic linker finds libopen62541
#    and libQt6OpcUa at runtime without installing them system-wide.
set(CMAKE_BUILD_RPATH "${QTOPCUA_INSTALL_DIR}/lib"
                      "${OPEN62541_INSTALL_DIR}/lib")

# 2. Plugin path: Qt's plugin loader doesn't know about our locally-built
#    QtOpcUa backend. Pass the path as a compile definition and call
#    QCoreApplication::addLibraryPath(QTOPCUA_PLUGIN_PATH) in main.cpp
#    *before* creating the QGuiApplication.
