问题是，我应该把这两条指令写在工程的 CMakeLists.txt 还是 src 目录下的 CMakeLists.txt，把握一个简单的原则，在哪里 ADD_EXECUTABLE 或 ADD_LIBRARY， 如果需要改变目标存放路径，就在哪里加入上述的定义。 在这个例子里，当然就是指 src 下的 CMakeLists.txt 了。 4，如何安装。 安装的需要有两种，一种是从代码编译后直接 [OPTIONAL] ] [...]) 参数中的 TARGETS 后面跟的就是我们通过 ADD_EXECUTABLE 或者 ADD_LIBRARY 定义的 目标文件，可能是可执行二进制、动态库、静态库。 目标类型也就相对应的有三种，ARCHIVE 特指静态库，LIBRARY 特指动态库，RUNTIME 特指可执行目标二进制。 DESTINATION void HelloFunc(); #endif 在 lib 目录下建立 CMakeLists.txt，内容如下： SET(LIBHELLO_SRC hello.c) ADD_LIBRARY(hello SHARED ${LIBHELLO_SRC}) 三，编译共享库: 仍然采用 out-of-source 编译的方式，按照习惯，我们建立一个 build 目录，在 build
