Issue compiling third party libraries for HTML5

Better use cmake for that.
Create a new CMakeLists.txt in the dir above assimp source and turn off every importer/exporter you don’t need (less errors):

eg:

set( ASSIMP_BUILD_3DS_IMPORTER OFF CACHE BOOL "Build importer" )
add_definitions(-DASSIMP_BUILD_NO_3DS_EXPORTER)

at the beginning of the file i use:

set(CMAKE_STATIC_LIBRARY_SUFFIX ".bc")
set(CMAKE_C_FLAGS "-emit-llvm")

and at the end:

add_subdirectory( assimp )

but I can’t compile it with the engine, yet. There are still 3 linking errors:

ProcessResult.StdOut:     error: unresolved symbol: _ZN6Assimp8ImporterD1Ev
ProcessResult.StdOut:     error: unresolved symbol: _ZN6Assimp8Importer8ReadFileEPKcj
ProcessResult.StdOut:     error: unresolved symbol: _ZN6Assimp8ImporterC1Ev
