修改 CMake VS2010 输出目录

12 October 2014

CMake创建的project exe文件的输出目录中是包含 $CMAKE_RUNTIME_OUTPUT_DIRECTORY/$BUILD_TYPE/，$BUILD_TYPE(Release/Debug)查看CMake的源码，下面就是写入OutDir的代码(cmVisualStudio10TargetGenerator.cpp)

   ...
   this->WritePlatformConfigTag("OutDir", config->c_str(), 3);
  *this->BuildFileStream << outDir
                         << "</OutDir>\n";
   ...

加入以下代码

　//
  const char* defines = this->GeneratorTarget->GetProperty("COMPILE_DEFINITIONS");
  if ( defines )
      if ( strstr( defines, "__SKIP_BUIlD_TYPE_OUT_DIR__") )
          remove_build_type(outDir);
  //
  this->WritePlatformConfigTag("OutDir", config->c_str(), 3);
  *this->BuildFileStream << outDir
                         << "</OutDir>\n";
  ...


  // ../xxx/Release/  => /xxx/    
  void remove_build_type(std::string& dir) {
  
      std::string tmp = dir;
      int pos = tmp.length();
      pos--;
      int remove_count = 0;
      while( pos > 0  )
      {
          if ( tmp[pos] == '\\' )
             remove_count++;
          if ( remove_count >= 2 )
             break;
          pos--;
      }
      dir = tmp.substr(0,pos+1);      
 }

CMakeLists.txt加入

add_definitions( -D__SKIP_BUIlD_TYPE_OUT_DIR__ )
