Hi, Stefan, can you say more about this? If MidasConfig.cmake is part of the cmake distribution,
(did I understand you right here?) and is installed into a system-wide directory,
how can it know to use midas from /home/agmini/packages/midas or from /home/olchansk/git/midas?

Certainly we do not do system wide install of midas (into /usr/local/bin or whatever) because
typically different experiments running on the same computer use different versions of midas.

For ROOT, it looks as if for find_package(ROOT) to work, one has to add $ROOTSYS to the Cmake package
search path. This is what we do in our cmake build.

As for find_package() vs install(EXPORT), we may have the same situation as with my "make cmake",
where my one line solution is no good for people who prefer to type 3 lines of commands.

Specifically, the install(EXPORT) method defines the "midas" target which brings with it
all it's dependent include paths, libraries and compile flags. So to link midas you need
two lines:

include(.../midas/lib/midas-targets.cmake)
target_link_libraries(myexe midas)
target_link_libraries(myfrontend mfe)

whereas find_package() defines a bunch of variables (the best I can tell) and one has
to add them to the include paths and library paths and compile flags "by hand".

I do not know how find_package() handles the separate libmidas, libmfe and librmana. (and
the separate libmanalyzer and libmanalyzer_main).

K.O.
