CMake variable or property to discern betwen debug and release builds

Question

I want to set a CMake variable differently for debug and release builds. I have tried to use CMAKE_CFG_INTDIR like this:

IF(${CMAKE_CFG_INTDIR} STREQUAL "Debug")
    SET(TESTRUNNER DllPlugInTesterd_dll)
ELSE(${CMAKE_CFG_INTDIR} STREQUAL "Debug")
    SET(TESTRUNNER DllPlugInTester_dll)
ENDIF(${CMAKE_CFG_INTDIR} STREQUAL "Debug")

But this variable evaluates to $(OUTDIR) at the time CMake does its thing.

Is there a CMake variable I can use to discern between debug and release builds, or something along the lines of how TARGET_LINK_LIBRARIES where one can specify debug and optimized libraries?

EDIT: I cannot use CMAKE_BUILD_TYPE since this is only supported by make based generators and I need to get this working with Visual Studio.

You can define your own CMAKE_CFG_INTDIR

IF(NOT CMAKE_CFG_INTDIR)
 SET(CMAKE_CFG_INTDIR "Release")
ENDIF(NOT CMAKE_CFG_INTDIR)

IF(CMAKE_CFG_INTDIR MATCHES "Debug")

...Debug PART...

ELSE(CMAKE_CFG_INTDIR MATCHES "Debug")

...Release PART...

ENDIF(CMAKE_CFG_INTDIR MATCHES "Debug")

Then, when you call cmake add the Definition (-D):

cmake -DCMAKE_CFG_INTDIR=Debug /path/of/your/CMakeLists.txt

For targets, you have two solutions:

First one:

IF(CMAKE_CFG_INTDIR MATCHES "Debug")

TARGET_LINK_LIBRARIES(YOUR_EXE DllPlugInTesterd...)

ELSE(CMAKE_CFG_INTDIR MATCHES "Debug")

TARGET_LINK_LIBRARIES(YOUR_EXE DllPlugInTester...)

ENDIF(CMAKE_CFG_INTDIR MATCHES "Debug")

Second one:

IF(CMAKE_CFG_INTDIR MATCHES "Debug")

FIND_LIBRARY(DLL_PLUGIN DllPlugInTesterd_dll /path/of/your/lib)

ELSE(CMAKE_CFG_INTDIR MATCHES "Debug")

FIND_LIBRARY(DLL_PLUGIN PlugInTester_dll /path/of/your/lib)

ENDIF(CMAKE_CFG_INTDIR MATCHES "Debug")

Then for link

TARGET_LINK_LIBRARIES(YOUR_EXE ${DLL_PLUGIN}...)
