Subject: jemalloc cmake module

(shamelessly stolen from Blender)

libstdc++ memory allocator is broken:
	"Notes about deallocation. This allocator does not explicitly release memory."

The story:
https://www.zerotier.com/blog/2017-05-05-theleak.shtml

The solution?!
http://jemalloc.net/

No need to recompile, just install it and a simple test run:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1 inkscape
