It is a matter of time spent and ease of usage. Dealing with several files is undoubtedly more of an hassle than a single file, bundles are used everywhere on the IT world, they minimize mistakes and are more compact.
About the dependency you disabled the glc_lib which I don't need, I need QuaZip which is included in glc_lib under the 3rdparty directory. QuaZip is a very simple library compared to glc so the build time will be neglectable.
When the other issues are sorted out I can copy QuaZip to its own directory and build it standalone.
