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.
  
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.
