With 12.13.0 ./configure --help prints:
--shared-nghttp2 link to a shared nghttp2 DLL instead of static linking
--shared-nghttp2-includes=SHARED_NGHTTP2_INCLUDES
directory containing nghttp2 header files
--shared-nghttp2-libname=SHARED_NGHTTP2_LIBNAME
alternative lib name to link to [default: nghttp2]
--shared-nghttp2-libpath=SHARED_NGHTTP2_LIBPATH
a directory to search for the shared nghttp2 DLLs
nghttp2-1.39.2 installs libnghttp2.pc but not libnghttp2.pc . On my system pkg-config libnghttp2.pc --libs works and pkg-config nghttp2.pc --libs does not work.
./configure --shared-nghttp2 prints on my system:
Package nghttp2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `nghttp2.pc'
to the PKG_CONFIG_PATH environment variable
No package 'nghttp2' found
Apparently, ./configure has to search for libnghttp2.pc, but looks for nghttp2.pc.
