问题 My project requires a version of zlib that isn't present on all target machines, so I want to build zlib from source in my project. Then when I make my project, it should first build zlib so it can be linked to when compiling my project. One complication is that zlib requires configure to be run before make can be run. I'm not even sure where to start here. Is there functionality built in to Qt Creator for importing 3rd party library source code like this, or do I need to code out a custom

The cache is already there because I manually run CMake when needed. How can I make Qt Creator to never run CMake automatically ? 回答1: You can't. Qt Creator 4.3 uses cmake server-mode to get information out of cmake. For that it needs to start cmake, which in turn will need to configure and generate to fetch all
