Cherry pick the CMake warning fix used for future version of GLFW so that the CI stops complaining.

* Print an error if OpenGL 4.1 isn't supported (cf #56)

* fix typo

reenable debug device
fix d3d11 warnings

* NDI: Update to NDISDK 3
- use BGRX instead of BGRA (less bitrate)
- warning fixes

* NDI:  Env variable check, fixed lib dependendy, fixed whitespace

* Add install functionality for 'linux'

* RPATH modification should have also been wrapped in a 'linux' conditional.

* Wrap all the things.

* AND not OR

* Added syntax highlighting for mat2, mat3, mat4 and int datatypes

* Added bool data type for syntax highlighting

It forces real nWidth and nHeight and also resets settings sizes accordingly.

config.json will take care of this from now on.

* Change Linux font path if required

* Make the font paht choice at run (and not compilation)

* Fix (I hope so) win64 construction

* Downgrade c++ version

* Seems that all C++ version are unable to convert string to char *...

* Use a C-like file existence check and remove uneeded #ifndef

* Still a blind tentative to compile on windows

Add clipboard support for X11

also fix bug in cmake that was somehow syntactically correct (hurr)
