Summary0009822: Please expose: cmGlobalGenerator::GetExportSet at cmake level
DescriptionIt would be very nice if cmGlobalGenerator::GetExportSet was expose at cmake level. This would allow easily exporting a build tree, just as easily as exporting an install tree.

typicaly project:
add_executable(generator generator.c)
add_library(mylib mylib.c)


Compare code for install tree:
...
install(TARGETS generator DESTINATION lib/myproj/generators EXPORT myproj-targets)
install(TARGETS mylib DESTINATION lib/myproj EXPORT myproj-targets)
# in a single line to export all target attached to myproj-targets
install(EXPORT myproj-targets DESTINATION lib/myproj)
...
# myproj-targets.cmake, properly contains all targets attached to myproj-targets

while for a build-tree:

# need to initialize an empty file:
file(WRITE ${COSMO_BINARY_DIR}/CoSMoExports.cmake "")
# manually book-keep target that have been attached to myproj-targets
if(build_generator)
  export(TARGETS generator APPEND FILE ${bla}/CoSMoExports.cmake)
endif()
if(build_mylib)
  export(TARGETS mylib APPEND FILE ${bla}/CoSMoExports.cmake)
endif()
# There is no way we are not missing a target listed in myproj-targets


Thanks,

Perhaps

  install(TARGETS generator ... EXPORT myproj-targets)
  install(TARGETS mylib ... EXPORT myproj-targets)
  install(EXPORT myproj-targets DESTINATION lib/myproj)

  # Export targets included in myproj-targets installation:
  export(EXPORT myproj-targets FILE ${bla}/CoSMoExports.cmake)

?

That would be truly fantastic. In fact I initially thought this was implemented when I saw 'export(PACKAGE)'...

If you get a chance at implementing export(EXPORT), I'd like to volunteer for testing it.

For later reference, here is what I used to catch any missing SHARED lib:

if(EXISTS
    ${CMAKE_CURRENT_BINARY_DIR}/CMakeFiles/Export/${COSMO_INSTALL_CMAKE_DIR}/CoSMoTargets.cmake
    )
  file(READ
    ${CMAKE_CURRENT_BINARY_DIR}/CMakeFiles/Export/${COSMO_INSTALL_CMAKE_DIR}/CoSMoTargets.cmake
    ENT
    )
  STRING(REGEX REPLACE "\r?\n" ";" ENT "${ENT}")
  foreach(line ${ENT})
    string(REGEX MATCH "ADD_LIBRARY\\(.*SHARED IMPORTED\\)" m ${line})
    if( m )
      string(REGEX REPLACE "ADD_LIBRARY\\((.*) SHARED IMPORTED\\)" "\\1" out ${m})
      list(FIND COSMO_LIBRARIES ${out} out2)
      if( out2 EQUAL -1)
        message(FATAL_ERROR "Found the library /${out}/, while the complete list is: ${COSMO_LIBRARIES}")
      endif()
    endif()
  endforeach(line)
endif()

Sending issues I'm not actively working on to the backlog to await someone with time for them.

If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it:

 http://www.cmake.org/mailman/listinfo/cmake [^]

It's easy to re-activate a bug here if you can find a CMake developer or contributor who has the bandwidth to take it on.
