Arch Linux

Description:

In src/kpackage/private/packagejobthread.cpp, it relies on CMAKE_INSTALL_FULL_LIBEXECDIR_KF5 to locate the resolve handlers.

static QString resolveHandler(const QString &scheme)
{
QString candidatePath = QStringLiteral(CMAKE_INSTALL_FULL_LIBEXECDIR_KF5 "/kpackagehandlers/%1handler").arg(scheme);
if (qEnvironmentVariableIsSet("KPACKAGE_DEP_RESOLVERS_PATH")) {
candidatePath = QStringLiteral("%1/%2handler").arg(qgetenv("KPACKAGE_DEP_RESOLVERS_PATH"), scheme);
}
return QFile::exists(candidatePath) ? candidatePath : QString();
}

If the cmake parameter is not given, the candidatePath would be /usr/lib/libexec/kf5 by default, however the folder is actually located in /usr/lib/kf5.

This issue breaks the installations of all packages that requires "kns://" or "appstream://" dependencies. Linking /usr/lib/kf5 to /usr/lib/libexec/kf5 temporarily resolves the issue.

Additional info:
* package version: kpackage 5.31.0-1

Steps to reproduce:
1. Run "kcmshell5 kcm_lookandfeel"
2. Install a Look and Feel package, e.g. ELPlas
3. Fails. Error code 4.
