Cmake能生成一个同时支持调试和发布的makefile吗

看起来我们需要为每个构建类型（调试/发布）创建单独的文件夹，在每个构建类型上运行cmake，并为调试/发布配置生成单独的makefile。有没有可能使用cmake创建一个单独的makefile，它同时支持调试/发布配置，当我们实际运行“make”时，它将为中间产品和最终产品创建单独的文件夹（如dll，exe）。

据我所知，这不能通过使用一组构建脚本来实现。然而，你可以做的是在你的工作区域有两个子目录：

build/
build/debug
build/release

然后执行：

$ cd build
$
$ cd build/debug
$ cmake -DCMAKE_BUILD_TYPE=Debug ../..
$ make
$
$ cd ../release
$ cmake -DCMAKE_BUILD_TYPE=Release ../..
$ make

如有必要，您可以在build目录中添加另一个构建脚本，如下所示：

#!/bin/sh
cd debug   && make && cd ..
cd release && make && cd ..

这可以使用ADD_CUSTOM_TARGET命令来实现。例如，如果要在makefile中添加调试和发布目标，请将以下内容添加到CMakeLists.txt文件中：

ADD_CUSTOM_TARGET(debug
  COMMAND ${CMAKE_COMMAND} -DCMAKE_BUILD_TYPE=Debug ${CMAKE_SOURCE_DIR}
  COMMAND ${CMAKE_COMMAND} --build ${CMAKE_BINARY_DIR} --target all
  COMMENT "Creating the executable in the debug mode.")

ADD_CUSTOM_TARGET(release
  COMMAND ${CMAKE_COMMAND} -DCMAKE_BUILD_TYPE=Release ${CMAKE_SOURCE_DIR}
  COMMAND ${CMAKE_COMMAND} --build ${CMAKE_BINARY_DIR} --target all
  COMMENT "Creating the executable in the release mode.")

然后，在使用cmake进行配置之后，可以在同一目录中运行make debug来设置调试目标，并运行make release来设置发布目标。

感谢@a.sam的回答，我现在可以提供一个独立的工作示例;你可以以后再谢我:)
本质上，这里我发明了一个CMAKE_BUILD_TYPE，它不存在于cmake中（cmake不知道它），这里称为SingleBuildDir，并使用它来区分创建顶级Makefile或调试/发布Makefile。
只需保存下面的文件作为CMakeLists.txt某处：

# instead of calling the following in build subdir, as we used to:
# cmake.exe  ../ -DCMAKE_BUILD_TYPE=Debug -G "MSYS Makefiles"
# now we want to try something like:
# cmake.exe  ../ -DCMAKE_BUILD_TYPE=SingleBuildDir -G "MSYS Makefiles"
# ... and then have `make debug` build in build/Debug, and `make release` build in build/Release
