I've checked that both the source and target files exist and are

It looks as thought you might be missing some escaped double-quotes.
I've tried quite a few quoting permutations, none work.
INSTALL(CODE
EXECUTE_PROCESS (COMMAND cat
\${CMAKE_CURRENT_SOURCE_DIR}/onejar_classpath.txt\
\${CMAKE_INSTALL_PREFIX}/onejar/boot-manifest.mf\)
)
Unfortunately this doesn't work.
AFAIK, this is because EXECUTE_PROCESS() doesn't fork a shell to run
the COMMANDs, so the redirection operators like are meaningless.
It's also worth noting that this is not a cross-platform command.
Yup, we're a unix only shop.
Then use one of the premier *nix tools:
INSTALL(CODE EXECUTE_PROCESS(COMMAND sh -c \cat
\\\${CMAKE_CURRENT_SOURCE_DIR}/onejar_classpath.txt\\\
\\\${CMAKE_INSTALL_PREFIX}/onejar/boot-manifest.mf))
Regards,

Maybe
look at file(READ ...) followed by file(APPEND ...)?
Looks promising, I'll check this out.
Thanks for the help Aaron.

Eek, that's a lot of quoting. I found a workaround but thanks for
this, I may use it if opportunity arises in the future. Perhaps this:

could be entered into the documentation somewhere as this is important
to know. Thanks for the help Michael.
