kripken Remove assertion on EMSCRIPTEN_ROOT (#6924) 
* remove assertion on EMSCRIPTEN_ROOT - on windows we have seen failures due to C:\PROGRA~1 being the same as C:\Program Files (despite the strings differing), and there is no simple way to check that. On other platforms links may cause similar issues, so it's not worth it

* remove tests for invalid EMSCRIPTEN_ROOT [ci skip]

Build Status CircleCI

Emscripten is an LLVM-to-JavaScript compiler. It takes LLVM bitcode - which can be generated from C/C++, using llvm-gcc (DragonEgg) or clang, or any other language that can be converted into LLVM - and compiles that into JavaScript, which can be run on the web (or anywhere else JavaScript can run).

License

Emscripten is available under 2 licenses, the MIT license and the University of Illinois/NCSA Open Source License.

Both are permissive open source licenses, with little if any practical difference between them.

The reason for offering both is that (1) the MIT license is well-known, while (2) the University of Illinois/NCSA Open Source License allows Emscripten's code to be integrated upstream into LLVM, which uses that license, should the opportunity arise.

See LICENSE for the full content of the licenses.
