# build_qt_static.sh
#
# Downloads and builds a minimal static Qt installation for CFGEditorPlusPlus.
# The project only uses Qt::Widgets, so only qtbase is needed (Core + Gui + Widgets).
#
# Usage:
#   ./build_qt_static.sh [install_prefix]
#
# Default install prefix: <script_dir>/6.11.0/static
#
# After a successful build, compile the project with:
#   cmake -S . -B build \
#       -DCFGEDITOR_BUILD_STATIC=ON \
#       -DSTATIC_QT_DIR=<install_prefix> \
#       -DCMAKE_BUILD_TYPE=Release
#   cmake --build build --parallel
