Since #1176, our CMake package configuration file makes enable_language({C,CXX,Fortran}) calls on behalf applications using find_package(ADIOS2). This causes such applications to require a Fortran compiler even if they do not themselves use Fortran or link to any ADIOS2 Fortran binding libraries.
Remove the enable_language() calls from our package configuration file. Applications should enable whatever languages they are using. If any problem the EDIT: Filter our own usage requirements to avoid referencing languages that are not enabled by the application.enable_language() calls were addressing comes up again, we can consider other solutions.
Fixes: #1885
