[oe] Qt5 meta and HostBinaries path

[Svein Seldal]

Hi

I am porting a large Qt5 application to Yocto and are using the meta-qt5 
layer. I have discovered that the qmake conf file, qt.conf, sets most 
Host* fields to the absolute host/sysroot path as expected. However, 
HostBinaries is not; It is set to /usr/bin/qt5, which cause our Qt5 app 
to fail compiling.

My first reaction is that this is clearly a bug, but after sifting 
through the codebase and googling about it, I am not so sure. I see that 
oe adds a new ExternalHostBinaries setting, and that this contains what 
HostBinaries would.

Can someone please explain if this is intentional and why its done like 
this?


Best regards,
