CMAKE add_custom_command：如何使用我的原始命令 [英] CMAKE add_custom_command: How to use my raw commands

问题描述

我想使用 ADD_CUSTOM_COMMAND 向我的 vc2010 项目添加一些自定义生成命令。但是：

[1] 我只是发现CMAKE会自动插入比我预期的更多的代码。

例如，我想要的命令是：

  c：\Some Folder\MyTool.exe-arg0 -arg1 
  

CMakeLists.txt如下：

  add_custom_command（OUTPUT $ {outfile} 
 COMMANDc：\Some Folder\\ \\ MyTool.exeARGS-arg0 -arg1
＃COMMAND\c：\一个文件夹\MyTool.exe \将失败，将被解析！
 MAIN_DEPENDENCY $ { infile} 
 VERBATIM）
  

但实际上我有：

  setlocal 
c：\Some Folder\MyTool.exe-arg0 -arg1
如果％errorlevel％neq 0 goto：cmEnd 
：cmEnd 
 endloca& call：cmErrorLevel％errorlevel％& goto：cmDone 
：cmErrorLevel 
退出/ b％1 
：cmDone 
如果％errorlevel％neq 0 goto：VCEnd 
  pre> 
 
 
这不是我想要的。我也试过字符串： COMMAND\$ {MYTOOL_PATH} \-arg0 -arg1，但是CMake刚刚无法解析它，因为有一个报价在字符串前面。 
所以很不好我不能引用命令字符串，因为路径  c：\Some Folder\MyTool.exe  包含空格。
 
 
 
  [2] 我也注意到CMake会自动扩展我的依赖项。 
 
 
 
如果我添加到命令 DEPENS$（PATH_MACRO），我将最终自动获得依赖关系路径由CMake扩展： C：\MySolutionDir\ $（PATH_MACRO）;但我只想要 $（PATH_MACRO），因为我会确保visual studio理解 $（PATH_MACRO）

解决方案
对于问题1，请尝试c：\\一些文件夹\\MyTool.exe-arg0 -arg1 。不需要 ARGS 参数，但要点是省略 -arg0 -arg1 周围的引号。 / p> 
 
 
对于问题2，由于 $（PATH_MACRO）不是绝对路径，CMake将其视为相对于您的源目录。解决这个问题的最好方法可能是使用生成器表达式，但没有关于您的具体情况的进一步信息，我无法提供更好的答案。

I am trying to add some custom build commands to my vc2010 project by using ADD_CUSTOM_COMMAND. But:

[1] I just find that CMAKE will automatically insert much more code than I hvae expected. 

For example, I want the command exactly to be:
"c:\Some Folder\MyTool.exe" -arg0 -arg1
The corresponding code in CMakeLists.txt is like:
add_custom_command( OUTPUT ${outfile}
                  COMMAND "c:\Some Folder\MyTool.exe" ARGS "-arg0 -arg1"
                  # COMMAND "\"c:\Some Folder\MyTool.exe\"" will FAIL to be parsed!
                  MAIN_DEPENDENCY ${infile}
                  VERBATIM)
but actually I got:
setlocal
c:\Some Folder\MyTool.exe "-arg0 -arg1"
if %errorlevel% neq 0 goto :cmEnd
:cmEnd
endlocal & call :cmErrorLevel %errorlevel% & goto :cmDone
:cmErrorLevel
exit /b %1
:cmDone
if %errorlevel% neq 0 goto :VCEnd
This is not what I want.  I have also tried the string: COMMAND "\"${MYTOOL_PATH}\" -arg0 -arg1", but CMake just failed to parse it because there is a quote in front of the string.
So it's bad I can't quote the command string because the path c:\Some Folder\MyTool.exe contains spaces.

[2] I also notice CMake will automatically expand my dependency pathes. 

If I add to the command DEPENS "$(PATH_MACRO)", I will eventually get the dependency path automatically expanded by CMake: C:\MySolutionDir\$(PATH_MACRO); But I only want $(PATH_MACRO), because I will make sure visual studio understands what $(PATH_MACRO)  refers to.

So here is my question:

How can CMake only accept my raw inputs, without auto expanding the path or inserting code I don't expect? I will make sure my inputs will be valid for visual studio. Thanks!

解决方案
For issue 1, try "c:\\Some Folder\\MyTool.exe" -arg0 -arg1.  The ARGS parameter isn't required, but the point is to omit the quotes around the -arg0 -arg1.

For issue 2, since $(PATH_MACRO) is not an absolute path, CMake sees it as a path relative to your source directory.  The best way to resolve this is probably to use "generator expressions", but without further info on your exact case, I can't provide a better answer.

For info on generator expressions, see the docs for add_custom_command.
