可以参考网上手动下载cmake的源码包进行安装，http://www.cmake.org/download/
解压后运行sudo ./bootstrap && sudo make && sudo make install
但是在执行./bootstrap的时候报以下错误：
/Users/baidu/cmake-3.9.0/Source/cmSystemTools.cxx:2061:39: error: expected ‘;‘ after expression exe_dir = CMAKE_BOOTSTRAP_BINARY_DIR "/bin"; ^ ; /Users/baidu/cmake-3.9.0/Source/cmSystemTools.cxx:2061:13: error: use of undeclared identifier ‘CMAKE_BOOTSTRAP_BINARY_DIR‘ exe_dir = CMAKE_BOOTSTRAP_BINARY_DIR "/bin"; ^ /Users/baidu/cmake-3.9.0/Source/cmSystemTools.cxx:2121:28: error: use of undeclared identifier ‘CMAKE_BOOTSTRAP_SOURCE_DIR‘ cmSystemToolsCMakeRoot = CMAKE_BOOTSTRAP_SOURCE_DIR; ^ /Users/baidu/cmake-3.9.0/Source/cmSystemTools.cxx:2061:40: warning: expression result unused [-Wunused-value] exe_dir = CMAKE_BOOTSTRAP_BINARY_DIR "/bin"; ^~~~~~ 1 warning and 3 errors generated. make: *** [cmSystemTools.o] Error 1 --------------------------------------------- Error when bootstrapping CMake: Problem while running make --------------------------------------------- Log of errors: /Users/baidu/cmake-3.9.0/Bootstrap.cmk/cmake_bootstrap.log ---------------------------------------------
在网上找了好久也没有找到解决办法，遂决定采用brew来安装了。brew是个什么东东呢？其实就是linux系统下面的apt-get、yum神器。
安装brew只需要一条命令即可：
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
这就成了，brew就用下面3条命令即可：
搜索软件：brew search 软件名，如brew search wget
安装软件：brew install 软件名，如brew install wget
卸载软件：brew remove 软件名，如brew remove wget
bogon:wabase iwaimai$ brew search cmake
==> Searching local taps...
cmake
==> Searching taps on GitHub...
caskroom/cask/cmake
==> Searching blacklisted, migrated and deleted formulae...
bogon:wabase iwaimai$ brew install cmake
==> Downloading https://homebrew.bintray.com/bottles/cmake-3.10.2.high_sierra.bottle.tar.gz
######################################################################## 100.0%
==> Pouring cmake-3.10.2.high_sierra.bottle.tar.gz
==> Caveats
Emacs Lisp files have been installed to:
/usr/local/share/emacs/site-lisp/cmake
==> Summary
?? /usr/local/Cellar/cmake/3.10.2: 2,334 files, 32.4MB
这就算是安装好了cmake了
