如何在CMake中指定Unix生成器？

Question

我编译LLVM-7是为了编译bcc，因为有一个命令来编译llvm-7，它是

cmake -G <generator> [options] <path to llvm sources>

我不知道如何指定<generator>。假设我想使用Unix Makefiles作为生成器，上面的命令是什么，我希望将llvm-7安装在/usr/lib/llvm-7/目录中，如何实现这一点。有人知道这个吗？

当我试着像

  cmake -G Unix Makefile ./

它会引起错误

 Makefile ./
CMake Error: Could not create named generator Unix

Generators
* Unix Makefiles               = Generates standard UNIX makefiles.
  Green Hills MULTI            = Generates Green Hills MULTI files
                                 (experimental, work-in-progress).

  CodeBlocks - Unix Makefiles  = Generates CodeBlocks project files.
  CodeLite - Ninja             = Generates CodeLite project files.
  CodeLite - Unix Makefiles    = Generates CodeLite project files.
  Sublime Text 2 - Ninja       = Generates Sublime Text 2 project files.
  Sublime Text 2 - Unix Makefiles

  Kate - Ninja                 = Generates Kate project files.
  Kate - Unix Makefiles        = Generates Kate project files.
  Eclipse CDT4 - Ninja         = Generates Eclipse CDT 4.0 project files.
  Eclipse CDT4 - Unix Makefiles= Generates Eclipse CDT 4.0 project files.

将生成器的名称放在引号中，如

cmake -G "Unix Makefiles" ..

您可以在-G之后省略一个空格并使用单引号。

[医]克郎氏文献在步骤3中包含了这一点：

cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm

此示例演示如何添加更多选项--在-D之后传递标志。若要设置安装前缀，必须将CMAKE_INSTALL_PREFIX设置为

cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=<install_path> ../llvm
