meta-qt5 yocto layer not compile on qt release 5.15.2 - yocto

Question

I cannot build my yocto distro (from 'pyro' version) when upgrade the meta-qt5 to the Qt version 5.15.2: I checkout the repository of meta-qt5 to the master branch that now support the qt 5.15.2, but I got some error on configuration about openssl and pcre2.
I'm using a container with ubuntu 18.04 as build system (to have the openssl version 1.1.1 as required by QT5.15.x) but I cannot solve that errors during the build of qtbase recipe:
| ERROR: Feature 'system-pcre2' was enabled, but the pre-condition 'libs.pcre2' failed.
|
| ERROR: Feature 'openssl-runtime' was enabled, but the pre-condition '!features.securetransport && !features.schannel && libs.openssl_headers' failed.
| WARNING: exit code 3 from a shell command.
I tried to comment the pcre and openssl packegeconfig into the qtbase recipe (to workaround that problems) but it didn't solve it.
The configuration return:

Answer 1

Try to use OpenSSL of honister (or any other poky that uses OpenSSL 1.1.x) and overwrite the prefered version of openssl in poky/meta/conf/distro/include/default-versions.inc.
Could be that you have to change the new Yocto x:append syntax back to the old x_append, depending on what Yocto version you take the OpenSSL recipe from.
