I built a beta-version of the FindPantheios.cmake (see attached version,
no copyright stuff, I'm sorry), it works - at least on windows and in my
configuration.
As I am new to this and this is my first try with Find* files, could
those experienced in the art of CMakeing please have a look at it, give
me some tips & tricks?
Suggestions welcome ;)
Another thing: I understand the function find_library is to be used to
"find" libs - the docs did not help me with understanding the naming
scheme used. Is it possible to use find_library to locate e.g.
"pantheios.1.core.vc10.x64.dll.debug.lib" if I have the string
"pantheios.1.core" and also ".dll.debug"? I do not know anything about
the part in the middle nor the ending. Sorry if this is a stupid question :/
My current solution is not very pretty and more of a hack and will only
work in Windows as it uses FILE GLOB.
Third question: Is there an easy way to deal with the singular/plural
variables, for example _INCLUDE_DIR and _INCLUDE_DIRS? How exactly is
the syntax for setting those (String, List, etc)?
Thank you for your time, help and patience

Thanks for the tip, I implemented that.
