Failed native build on Ubuntu due to "missing" library liblwjgl.so

[jeffersonheard]

I'm on Ubuntu 18.04. Executing clj -A:dev dev.clj native gave me the following error:

Downloading: nightlight/nightlight/maven-metadata.xml from https://repo.clojars.org/

[LWJGL] Failed to load a library. Possible solutions:
	a) Add the directory that contains the shared library to -Djava.library.path or -Dorg.lwjgl.librarypath.
	b) Add the JAR that contains the shared library to the classpath.
[LWJGL] Enable debug mode with -Dorg.lwjgl.util.Debug=true for better diagnostics.
[LWJGL] Enable the SharedLibraryLoader debug mode with -Dorg.lwjgl.util.DebugLoader=true for better diagnostics.

That is not the correct command; please see the readme file in the generated project. If you want to run the native version, you'll need to do clj -A:dev:linux dev.clj native, and for the web version it is clj -A:dev dev.clj.

Ah you're right. I was reading the README on play-cljc. Thank you!

Ah I see, I'll update the readme when I get the chance, to help avoid confusion. Thanks.
