[CMake] Resolving CMP0026 warnings

[Knox, Kent]

Hi all~

I have a question similar to one recently asked by NoRulez about CMP0026.  I've been working on updating my legacy cmake code to compile without warnings with the 3.x series.

When I install my projects, I want to copy my 'non-system' target dependencies to help debug on non-development machines.  A while back, I stumbled on the get_prerequisites( ) cmake function, which helps me enumerate target dependencies.  http://www.cmake.org/cmake/help/v3.1/module/GetPrerequisites.html

My code is based on the solution posted by a Timothy M. Shead here:
http://www.cmake.org/pipermail/cmake/2009-June/029975.html

The problem is that get_prerequisites( ) needs a path to the target.  How do I now get this path without calling the LOCATION property?  I don't know where I can use a generator expression.

=====================================
CMakeLists.txt
====================================
get_target_property( libraryLocation myHumbleLibrary LOCATION )

configure_file(
    "${CMAKE_CURRENT_SOURCE_DIR}/copyLibraryDependencies.cmake.in"
    "${CMAKE_CURRENT_BINARY_DIR}/copyLibraryDependencies.cmake"
    @ONLY
)

# Register script at run at install time to analyze the executable and copy dependencies into package
install( SCRIPT "${CMAKE_CURRENT_BINARY_DIR}/copyLibraryDependencies.cmake" )

=====================================
copyLibraryDependencies.cmake.in
=====================================
# The Microsoft IDE presents a challenge because the full configuration is not known at cmake time
# This logic allows us to 'substitute' the proper configuration at install time
if( "${CMAKE_INSTALL_CONFIG_NAME}" MATCHES "Debug" )
    string( REPLACE "\$(Configuration)" "Debug" fixedLibraryLocation "@libraryLocation@" )
endif( )

...

# This retrieves a list of shared library dependencies from the target; they are not full path names
# Skip system dependencies and skip recursion
get_prerequisites( ${fixedLibraryLocation} libraryDependencies 1 0 "" "" )

# Loop on queried library dependencies and copy them into package
foreach( dep ${libraryDependencies} )
...
endforeach( )

Thanks for any help,
Kent
