总结CMake
本文参考 知乎回答：https://www.zhihu.com/question/58949190/answer/999701073 如何写CMakeList.txt C++工程的setup Learn CMake’s Scripting Language in 15 Minutes 入门 CMake的目的：It’s all about targets Define a target: defines targets using the add_executable, add_library or add_custom_target commands. Define the target’s properties: Once a target is created, it has properties that you can manipulate using the get_property and set_property commands. All target properties are strings. In CMake, every variable is a string. Other target properties include LINK_LIBRARIES, INCLUDE_DIRECTORIES and COMPILE_DEFINITIONS. Those…
CMakeList.txt: 六个例子
我们已经在C++工程的setup提到过，CMake是build system的生成器，它用于生成makefile，然后make就可以使用生成的make file对c++工程进行编译和链接成可执行文件。The make utility and Makefiles provide a build system that can be used to manage the compilation and re-compilation of programs that are written in any programming language. I use Makefiles quite often in my projects to automate the build process; however, there are times when Makefiles become overly complex for the task. Building complex projects is…
CMake-based C++工程

HPP, FCL and Pinocchio
FCL(Flexible Collision Library) FCL是Flexible Collision Library的缩写，是A General Purpose Library for Collision and Proximity Queries，它具体的github repo在这里，相关的学术文章为FCL: A general purpose library for collision and proximity queries。 FCL is also used as the collision checking library for grasping and manipulation pipeline implemented on a PR2. In the course of the task, the overall algorithm makes multiple calls to…
