build problem with CMAKE_OSX_ARCHITECTURES var #945
Description
Hi on a Kodi software library we are using bento4
but our build system already set the CMAKE_OSX_ARCHITECTURES var
recently with commit cbea428
has been added this line
Line 17 in 525027c
that set the CMAKE_OSX_ARCHITECTURES looks like that overwrite our config value, and cause to failed build of bento4
can you implement a logic to avoid to change/overwrite an existing CMAKE_OSX_ARCHITECTURES value?
