wasm: allow apps to override EXPORT_RUNTIME_METHODS
Developers can add to Emscripten's EXPORT_RUNTIME_METHODS
by defining their own using:
QT_WASM_EXTRA_EXPORTED_METHODS
Which will add on to Qt's default exported runtime methods
of UTF16ToString,stringToUTF16
for cmake:
set_target_properties(<target> PROPERTIES QT_WASM_EXTRA_EXPORTED_METHODS "ccall,cwrap")
or
set(QT_WASM_EXTRA_EXPORTED_METHODS "ccall,cwrap")
for qmake:
QT_WASM_EXTRA_EXPORTED_METHODS = ccall,cwrap
Done-with: Mikolaj Boc
Fixes: QTBUG-104882
Pick-to: 6.4
Change-Id: I9678bdb7b077aaa8527057212ea4e161c0be0b60
