Conan-center-index: [package] libnghttp2/1.39.2: not building with Linux Clang 9

[danimtb]

The recipe for libnghttp2/1.39.2 does not build under Linux Clang 9.

After generating all the index packages for Clang 9, the ones for this library failed to compile.

Related to #211

Package and Environment Details (include every applicable attribute)

• Package Name/Version: libnghttp2/1.39.2
• Operating System+version: Linux Ubuntu 18.04
• Compiler+version: Clang 9
• Conan version: conan 1.21.0
• Python version: Python 3.7.4

@danimtb during the build I found:

configure: WARNING: Package 'cunit', required by 'virtual:world', not found
checking for CU_initialize_registry in -lcunit... no
checking for ev_time in -lev... yes
checking ev.h usability... yes
checking ev.h presence... yes

checking for OPENSSL... no
configure: Package 'ZLIB', required by 'openssl', not found
checking for LIBCARES... yes
checking for LIBEVENT_OPENSSL... yes
checking for JANSSON... yes

configure: error: applications were requested (--enable-app) but dependencies are not met.

This fix requires https://github.com/conan-io/conan/issues/6222
