[CMake] How to build a target on install (only)?

[David Cole]

The other way you could approach this, but which would not be as
simple would be to invent *your own* custom install target
(install_with_dSYM, or whatever name makes sense to you). Then you
could have that target depend on all the custom targets that build the
dSYM files. When you build this custom install_with_DSYM target, it
would first build all the dSYM files via add_custom_command rules, and
*then* run the same command that "make install" runs to install all
the other files. Or vice versa, if the dSYM needs to be run on stuff
in the install tree...
