[CMake] Adding a target to 'all' that was previously excluded

[Andrew White]

How do I add an excluded (executable) target to the build. I know that if I add a library EXCLUDE_FROM_ALL and then create a dependency on that library then that the library will be built anyway. How do I trigger similar behaviour from an executable target?

Example:

Directory A contains a CMakeLists.txt that builds half a dozen utilities. As part of my project, I want to add a single target from that list.

I can include the build info without auto-adding all targets by going:

Add_subdirectory(blah EXCLUDE_FROM_ALL)

How do I then add target blah_X to my 'all' build? Or is there another way to approach this?

Thanks

You can use a new target, built by all, depending on your initial target:

add_custom_target(build_blah_X ALL)
add_dependencies(build_blah_X blah_X)

Hi Andrew.

All that the EXCLUDE_FROM_ALL argument of add_executable() does is set that
target's property EXCLUDE_FROM_ALL to TRUE. So all you need to do is set
that property to false again:

set_property(TARGET blah PROPERTY EXCLUDE_FROM_ALL FALSE)
