Summary0012543: Cannot specify link_libraries per configuration when using custom configurations
DescriptionRelated to 0012124, added to refine the requirement.

In my project, I need to build a particular shared project a number of different ways (Debug/Release Shared/Static MBCS/Unicode in all combinations). These are implemented as multiple configurations via CMAKE_CONFIGURATION_TYPES. (Debug, Debug-Shared, Debug-Shared-Unicode for example)

At the project level, I need to specify different support libraries by name, based on the configuration. For example, for static debug I reference cppunitd.lib, and for shared debug I reference cppunitd-sh.lib.

The support for conditional libraries in the target_link_libraries command is limited to the standard configurations, Debug, Release, Optimized. Custom configurations are not recognized here.

What is needed is the ability to use custom configurations in the target_link_libraries command to set library names per configuration.

The same argument applies to setting the library path (and to a lesser extent, the include path). Currently, these can only be set per-configuration at the solution level (via set(CMAKE_CXX_FLAGS_DEBUG_SHARED_UNICODE) ), which requires that the conditional paths for all libraries in the solution be set globally. This results in a potentially dangerous superset of LIBPATHS being pushed into every project in the solution, and loss of control over order and precedence.
  
Steps To Reproduce
Additional Informationto summarize, looking for features as follows :

target_link_libraries ( {MyCustomConfigName} {MyLibByConfigName} )

link_directories ( {MyCustomConfigName} {MyLibPath} )

include_directories ( {MyCustomConfigName} {MyIncPath} )

That should already be possible using an imported library

add_library(mylib UNKNOWN IMPORTED)
set_target_properties(mylib PROPERTIES
  IMPORTED_LOCATION_DEBUG "/path/to/debug"
  IMPORTED_LOCATION_UNICODE "/path/to/unicode"
  ... etc... )

..

target_link_libraries(myexecutable mylib)

You can also set compile flags on a per-configuration bases on the targets.

Feel free to ask for more help on the mailing list.
(and avoid deprecated things like 'link_directories()')

Tried and working. I should have posted the issue to the list first :) Thanks Clinton.
