I've started using fixup_bundle(). One of the things that occurs to me
is that much of the information that needs to go into fixup_bundle()
arguments (executables and library directories) can be gleaned from
arguments to add_executable() and target_link_libraries().
It might be nice to extend these two standard functions to create
variables that could be used with fixup_bundle. I could see writing
macros or functions to wrap this up for my projects, but I think it
might belong in the "standard" versions of these.
Perhaps this already exists and I have simply not seen it?
I'd like to get to a world where we could do something like:
# tell CMake to remember the executable names and libraries for each
set(CMAKE_BUILD_FIXUP_ARGS ON)
add_executable(execName ... BUNDLEME)
target_link_libraries(execName lib1 lib2 ...)
install(TARGETS execName ... )
add_executable(progName ... BUNDLEME)
target_link_libraries(progName lib1 lib18 ...)
install(TARGETS execName ...)
fixup_bundle(${CMAKE_INSTALL_TARGETS}
""
${CMAKE_execName_LIBPLACES} ${CMAKE_progName_LIBPLACES})
I'm speculating that it is target_link_libraries that I would extend
with the capability to generate the lists of library locations (some
code and conventions required for DLL platforms). I could see some
people wanting to avoid bundling executables they do not want to
install, so a flag for add_executable to indicate whether to bundle
seems like it would work.
In any case, this would allow you to do a fixup_bundle() as a POST_BUILD
stage so that things could be run from the build directory. This is
nice for testing prior to doing an install.
Thoughts?
