Hi,
sorry for the delay. I see you already found a solution yourself.
Still, I want to share mine:
---------------------CopyPrerequisites.cmake--------------------
include ( GetPrerequisites )
if ( NOT DEFINED PREREQ_FILE )
message ( FATAL_ERROR "PREREQ_FILE must be defined(${PREREQ_FILE})" )
endif ()
#
# Satisfy the find_file() search by common subdirs where .dll file can
be found
#
foreach ( dir ${CMAKE_PREFIX_PATH} )
list ( APPEND dirs ${dir}/bin )
endforeach ( dir )
get_filename_component ( COPY_DESTINATION "${PREREQ_FILE}" PATH )
get_prerequisites ( "${PREREQ_FILE}" COPY_FILES 1 1 "${dirs}"
"${COPY_DESTINATION}" )
foreach ( COPY_FILE ${COPY_FILES} )
if ( NOT IS_ABSOLUTE ${COPY_FILE} )
set ( COPY_FILE_FULL )
gp_resolve_item ( "${PREREQ_FILE}" "${COPY_FILE}" "${dirs}"
"${COPY_DESTINATION}" COPY_FILE_FULL )
else ()
set ( COPY_FILE_FULL ${COPY_FILE} )
endif ()
if ( COPY_FILE_FULL )
get_filename_component ( COPY_SOURCE_DIR "${COPY_FILE_FULL}" PATH )
if ( NOT COPY_SOURCE_DIR MATCHES "^${COPY_DESTINATION}$" )
message ( "Copying ${COPY_FILE_FULL} to output directory" )
execute_process ( COMMAND "${CMAKE_COMMAND}" -E
copy_if_different "${COPY_FILE_FULL}" "${COPY_DESTINATION}" )
endif ()
else ()
message ( "Failed to find ${COPY_FILE}" )
endif ()
endforeach ( COPY_FILE )
----------------------------------------------------------
This can now be called from CMakeLists.txt:
if ( CMAKE_RUNTIME_OUTPUT_DIRECTORY )
add_custom_command ( TARGET Gui POST_BUILD
COMMAND ${CMAKE_COMMAND}
"-DCMAKE_PREFIX_PATH:PATH=${SOME_SEARCH_DIRS}"
"-DPREREQ_FILE=$<TARGET_FILE:MyTarget>"
-P ${CMAKE_SOURCE_DIR}/CMakeModules/CopyPrerequisites.cmake
VERBATIM
)
endif ()
The variable SOME_SERACH_DIRS is filled with e.g. IMPORTED_LOCATION
property values.
The same variable is used when calling INSTALL(CODE ".....
fixup_bundle(...)" )
Regards,
HS
Zitat von lec...@gmail.com:
I managed to get it working by using an intermediate script.
One might want to generate the script instead of using the
« RUN_IT » variable trick.
This was only tested on Windows, but seems to work fine.
Put the following code in a xxxxxx.cmake file, include it from your
CMakeLists.txt and enjoy.
# This is a helper script to run BundleUtilities fixup_bundle as postbuild
# for a target. The primary use case is to copy .DLLs to the build
directory for
# the Windows platform. It allows generator expressions to be used
to determine
# the binary location
#
# Usage : run_fixup(TARGET LIBS DIRS)
# - TARGET : A cmake target
# - See fixup_bundle for LIBS and DIRS arguments
if(RUN_IT)
# Script ran by the add_custom_command
include(BundleUtilities)
fixup_bundle("${TO_FIXUP_FILE}" "${TO_FIXUP_LIBS}" "${TO_FIXUP_DIRS}")
# End of script ran by the add_custom_command
else()
set(THIS_FILE ${CMAKE_CURRENT_LIST_FILE})
message(${THIS_FILE})
function(run_fixup _target _libs _dirs)
message(${THIS_FILE})
add_custom_command(
TARGET ${_target} POST_BUILD
COMMAND ${CMAKE_COMMAND} -DRUN_IT:BOOL=ON
-DTO_FIXUP_FILE=$<TARGET_FILE:${_target}> -DTO_FIXUP_LIBS=${_libs}
-DTO_FIXUP_DIRS=${_dirs} -P ${THIS_FILE}
COMMENT "Fixing up dependencies for ${_target}"
VERBATIM
)
endfunction()
endif()

Objet :Re: [CMake] DLL handling under CMake
I'd also be interested in this. I saw an old mail in the ML about
this, but it seems fixup_bundle is old and cant use generator
expressions, making it hard to use (I don't want to hardcode the
executable path).
Do you have a sample for this ?
CMake would really benefit from having those features made more
accessible instead of everyone having to write its own script

This steps are tedious and I'm wondering if there is a mechanism that
exists or that have to be imagined to make the DLL nightmare end.
I use BundleUtilities to achieve the copying of DLL files to the
installation directory. The main problem for this is to enumerate
the needed directories.
I use the same for copying DLL files to the output directory to ease
debugging.
The advantage is the inspection of the exe for really needed DLL
files. This AUTOMATICALLY handles the case debug vs. release.
