Subject: HTTP3.md: avoid `configure` issue for ngtcp2 1.14.0+ compatibility
X-Git-Tag: curl-8_16_0~72
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3c64ffaff4cd8c8275627dd2e17b6879a1d32262;p=thirdparty%2Fcurl.git

HTTP3.md: avoid `configure` issue for ngtcp2 1.14.0+ compatibility

Applied the same workaround to the build examples as used earlier in CI.
That is, drop `<path> from `--with-ngtcp2=<path>` and configure env
`PKG_CONFIG_PATH` instead.

Till the root cause is fixed.
