In CMake, how do I work around the Debug and Release directories Visual Studio 2010 tries to add?

Question

I'm trying to build one of my CMake-based projects from a couple of years ago with Visual Studio 2010 and I'm running into problems to do with the output directory for a project. Visual Studio has always been very keen on adding Debug/ and Release/ subdirectories when outputting binaries, and for various reasons I've always been very keen on removing them - now that I'm using a new version of CMake and a new version of Visual Studio, the old workaround in CMake no longer seems to work, and I'm looking to find out the "new" way of doing it. With a previous version of CMake (2.6) and a previous version of Visual Studio (2008), I used the following: ``` IF(MSVC_IDE) # A hack to get around the "Debug" and "Release" directories Visual Studio tries to add SET_TARGET_PROPERTIES(${targetname} PROPERTIES PREFIX "../") SET_TARGET_PROPERTIES(${targetname} PROPERTIES IMPORT_PREFIX "../") ENDIF(MSVC_IDE) ``` This worked fine, but no longer seems to do the trick. Please does anyone know of a simila…

It depends a bit on what you want precisely, but I would recommend to take a look at the available target properties, similar to this question.

It depends a bit on what you want exactly. For each target, you could manually set the library_output_directory or runtime_output_directory properties.

```
if ( MSVC )
    set_target_properties( ${targetname} PROPERTIES LIBRARY_OUTPUT_DIRECTORY ${youroutputdirectory} )
    set_target_properties( ${targetname} PROPERTIES LIBRARY_OUTPUT_DIRECTORY_DEBUG ${youroutputdirectory} )
    set_target_properties( ${targetname} PROPERTIES LIBRARY_OUTPUT_DIRECTORY_RELEASE ${youroutputdirectory} )
    # etc for the other available configuration types (MinSizeRel, RelWithDebInfo)
endif ( MSVC )
```

You could also do this globally for all sub-projects, using something like this:

```
# First for the generic no-config case (e.g. with mingw)
set( CMAKE_RUNTIME_OUTPUT_DIRECTORY ${youroutputdirectory} )
set( CMAKE_LIBRARY_OUTPUT_DIRECTORY ${youroutputdirectory} )
set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${youroutputdirectory} )
# Second, for multi-config builds (e.g. msvc)
foreach( OUTPUTCONFIG ${CMAKE_CONFIGURATION_TYPES} )
    string( TOUPPER ${OUTPUTCONFIG} OUTPUTCONFIG )
    set( CMAKE_RUNTIME_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${youroutputdirectory} )
    set( CMAKE_LIBRARY_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${youroutputdirectory} )
    set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${youroutputdirectory} )
endforeach( OUTPUTCONFIG CMAKE_CONFIGURATION_TYPES )
```
