[CMake] Make target dependent on all executables & libraries

[Lezz Giles]

I don't think I can make a custom command depend on ALL.  Here's the relevant CMakeLists.txt fragment that I have now...

ADD_EXECUTABLE( hellow hellow.c )

ADD_CUSTOM_COMMAND(OUTPUT ${CMAKE_BINARY_DIR}/docs COMMAND cat ${CMAKE_SOURCE_DIR}/hellowdoc.template > ${CMAKE_BINARY_DIR}/docs)

ADD_CUSTOM_TARGET(documentation DEPENDS ${CMAKE_BINARY_DIR}/docs)

I want to make my custom_command dependent on the executable.  If I add "DEPENDS hellow" then it works, but as I said before, this is going to be shared across multiple projects.  If I add "DEPENDS ALL" or "DEPENDS all" then it interprets "all" as a filename and looks for "../all"

I can also use the second form of ADD_CUSTOM_TARGET, but then I need to tie it to one specific executable, not "all".

How about making it depend on the ALL target?

I want to use doxygen to generate documentation, but I also want it to only run if something has changed.  At first I was playing with the idea of having it be dependent on all source & header files, but I quickly realized that that would be difficult or impossible in cmake.  Then I realized that if any source files changed, at least one of my executables or libraries would rebuild, and so I could make my doxygen dependent on the executables & libraries.

Is there any simple way to get a list of all executables and libraries?  I was hoping for variables ALL_EXECUTABLES and ALL_LIBRARIES but unfortunately they don't exist.  The doxygen target will be added to a central cmake file that is shared by many projects so I'd like to have a solution that has little or no impact on the projects.  I know I can define my own ALL_TARGETS and just go to all the projects and assign to ALL_TARGETS, but this is not a good solution from a maintenance perspective.
