When "speex/speex_resampler.h" was included, another exported header (in dist/include) would find the speex/speex_resampler.h in dist/include before dist/system_wrappers. Visibility of undefined symbols depended on the order of includes. This patch changes includes to <speex/speex_resampler.h> so that WRAP_SYSTEM_INCLUDES works as expected but removes the wrapper when not using GKMEDIAS_SHARED_LIBRARY. --HG-- extra : rebase_source : 93ca1dbdd6b489647624326e78539f44c60d0b34
