For QLMesh (and some other projects), I am running my own fork of Asset Import Library. The difference: it is amalgamated build - all sources are merged into one file (including dependencies). Since Assimp recently switched to miniz, I have replaced remaining references to zlib with miniz - so zlib is not required too.

Everything you need to buid the assimp is:
g++ -c -std=c++11 code-portable/assimp.cpp
or just add assimp.cpp to your project/IDE (you can find
code-portable directory in my repo. One disclaimer: I have only tested this amalgamation under OSX with QLMesh). Main reason for this amalgamation is that it makes compilation/recompilation on different platforms with different configurations rather easier. Side-effect is that single-file
assimp.cpp compiles really fast (like 10x faster on my MacBook).
