Set cmake target name for debug and release configuration

Question

I am trying to differentiate between a debug and release build.

If a debug build is in progress I want to install myLib d in /usr/local/lib. If a release build is in progress I want to install myLib in /usr/local/lib.

Here is my approach

IF(CMAKE_BUILD_TYPE MATCHES RELEASE)
    SET(LIB_NAME myLib) 
ELSE()
    SET(LIB_NAME myLibd) 
ENDIF(CMAKE_BUILD_TYPE MATCHES RELEASE)

ADD_LIBRARY(${LIB_NAME} ${Source_files} ${Header_files})
INSTALL(TARGETS ${LIB_NAME} DESTINATION /usr/local/lib)

However, the target name is in both cases (CMAKE_BUILD_TYPE=Debug or Release) always myLib d . What is the problem here?

Answer 1

Solution

Set CMAKE_DEBUG_POSTFIX variable:

if(NOT CMAKE_DEBUG_POSTFIX)
  set(CMAKE_DEBUG_POSTFIX d)
endif()

Details

What is the problem here?

• You need to use if(CMAKE_BUILD_TYPE MATCHES Release) instead of if(CMAKE_BUILD_TYPE MATCHES RELEASE)
• Probably you need to clean build directory
• Note that if(CMAKE_BUILD_TYPE...) approach will not work for multi-configuration generators

Answer 2

set_property(TARGET ${LIB_NAME} PROPERTY DBG_POSTFIX d)
