cmake -DENABLE_STATIC_LIB=true -DENABLE_SHARED_LIB=false
make
make install

The library is built and installed as lib/libnghttp2_static.a, but the lib/libnghttp2.pc (and lib/pkgconfig/libnghttp2.pc) file says Libs: -L${libdir} -lnghttp2.

Since libcurl only knows how to find nghttp2 by finding its .pc and using the info there, I can't build it against a static nghttp2 unless I do something like sed -e"|-lnghttp2|-lnghttp2_static|" both copies of the .pc file after install.
