WebGL Viewer Sample: Emscripten no longer exports malloc

[siquus]

Description

Dear Open-Cascade Team,

Emscripten used to "accidentally" export malloc but no longer does (Emscripten changelog). As a consequence, when using a recent Emscripten version, the WebGL Viewer Sample's "Choose BREP file to upload" will fail to load a new brep file with the error "Uncaught TypeError: Module._malloc is not a function".

To fix this issue, add the following line to the CMakeLists.txt of that sample (ref. Emscripten docu):

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -s EXPORTED_FUNCTIONS=\"['_main', '_malloc']\"")

Thanks, Patrik

Expected Behavior

BREP file is loaded into the viewer.
