如何在CMake脚本中设置PATH环境变量？ [英] How to set PATH environment variable in CMake script?

问题描述

我想通过Mingw编译器构建我的源，不放在我的系统PATH。
我在我的脚本开始尝试这个：

  set（Env {PATH}c：/ MyProject / Tools / mingw / bin /c：/MyProject/Tools/mingw/msys/1.0/bin/）
  

$ b b

这样：

  set（CMAKE_PROGRAM_PATHc：/ MyProject / Tools / mingw / bin /c： /MyProject/Tools/mingw/msys/1.0/bin/）
 set（CMAKE_LIBRARY_PATHc：/ MyProject / Tools / mingw / bin /c：/MyProject/Tools/mingw/msys/1.0/bin /）
 set（CMAKE_SYSTEM_PROGRAM_PATHc：/ MyProject / Tools / mingw / bin /c：/MyProject/Tools/mingw/msys/1.0/bin/）
 set（CMAKE_SYSTEM_PREFIX_PATHc ：/ MyProject / Tools / mingw / bin /c：/MyProject/Tools/mingw/msys/1.0/bin/）
  

第一个变体根本不工作。建议我不能覆盖CMake脚本中的环境变量的值。
第二个脚本发现我的mingw编译器，但捕获错误，而运行gcc（找不到libgmp-10.dll它需要通过gcc）。这是因为PATH变量没有设置到我的Mingw。

解决方案

编写脚本文件以启动CMake。

在Windows上创建批处理文件：

  @echo off 
 path = c：\MyProject\Tools\mingw\bin; c：\MyProject\Tools\mingw\msys\1.0\bin 
C：\Program Files\ CMake 2.8 \bin\cmake-gui.exe
  

在Linux上创建一个bash脚本： / p>

  export PATH = $ PATH：/ your / path 
  

I want to build my sources by Mingw compiler wich in not placed on my system PATH. I tried this in the beginning of my script:

set(Env{PATH} "c:/MyProject/Tools/mingw/bin/" "c:/MyProject/Tools/mingw/msys/1.0/bin/")

And this:

set(CMAKE_PROGRAM_PATH "c:/MyProject/Tools/mingw/bin/"   "c:/MyProject/Tools/mingw/msys/1.0/bin/")
set(CMAKE_LIBRARY_PATH "c:/MyProject/Tools/mingw/bin/" "c:/MyProject/Tools/mingw/msys/1.0/bin/")
set(CMAKE_SYSTEM_PROGRAM_PATH "c:/MyProject/Tools/mingw/bin/" "c:/MyProject/Tools/mingw/msys/1.0/bin/")
set(CMAKE_SYSTEM_PREFIX_PATH "c:/MyProject/Tools/mingw/bin/" "c:/MyProject/Tools/mingw/msys/1.0/bin/")

The first variant doesn't work at all. A suggest that I can't overwrite the value of the environment variable in CMake script. The second script finds my mingw compiler, but catches the error while running gcc (can't find libgmp-10.dll which needs by gcc). This is because the PATH variable is not setted to my Mingw.

解决方案

Write a script file to start CMake.

On Windows make a batch file:

@echo off
set path=c:\MyProject\Tools\mingw\bin;c:\MyProject\Tools\mingw\msys\1.0\bin
"C:\Program Files\CMake 2.8\bin\cmake-gui.exe"

On Linux make a bash script:

export PATH=$PATH:/your/path
