I found a different solution which doesn’t require OSG changes at all:
-DCMAKE_DISABLE_FIND_PACKAGE_PythonLibs=1
I was completely unaware of this feature but one of my colleagues is a CMake
contributor and pointed it out. Essentially you disable and find(Foo) using
this style, unless it is REQUIRED - the only catch is the capitalization of the
suffix must match that using in the find() declaration precisely.
(Oh and it requires ‘fairly’ recent CMake - 2.8 at least)
Arguably making the options explicit in OSG is nicer to users however, since
this CMake option is obscure to say the least!
Kind regards,
James
