Running curl 7.36.0/configure --with-nghttp2 calls
CURL_CHECK_PKGCONFIG("libnghttp2", "/lib/pkgconfig") from acinclude.m4,
which effectively sets PKG_CONFIG_LIBDIR via CURL_EXPORT_PCDIR to
"/lib/pkgconfig", so that "pkg-config" isn't looking anymore in
/usr/lib64/pkgconfig and failes to find (there) libnghttp2, even if it is
perfectly correct installed.
Ack, the configure script wronly passes in a bad path when --with-nghttp2 is
used without a path - I suspect that is still an exception. Please see my
attached patch for a fix that I believe is correct. Please let me know if it
works for you too!
And btw, you might want curl from git or a daily snapshot and nghttp2 from git
to be fairly sure they both build and work together...
Thanks for your report!

Subject: [PATCH] configure: use the nghttp2 path correctly with pkg-config
When --with-nghttp2 was used (without a given path), the
PKG_CONFIG_LIBDIR varialbe could get clobbered and ruin a proper
detection of the library.
