I input command "emcmake cmake ..;make;"

Yes, I got this "error: expected top-level entity " too when compiling nanogui; I think it helps to see what it's doing if you turn on -D CMAKE_VERBOSE_MAKEFILE:BOOL=ON in the emcmake cmake call... ... /Users/ds/Development/miniforge3/bin/cmake -E cmake_link_script CMakeFiles/nanogui.dir/link.txt --verbose=1 /Users/ds/Development/emsdk/upstream/emscripten/em++ -o libnanogui.bc @CMakeFiles/nanogui.dir/objects1.rsp em++: warning: object file output extension (.bc) used for non-object output.

Apparently the 'warning' should be an error instead... Not sure where to 'fix' things, but emscripten appears to jump directly from the object file in 'objects1.rsp' to javascript instead of generating the requested bytecode (?).

In my case, using "emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.63 (217010a223375e6e9251669187d406ef2ddf266e)".
