[yocto] [Yocto][meta-qt5][qtwayland]Qtwayland recipe fails with Yocto 2.5

[Priyanshu Sharma]

Hi All,

I'm consistently getting a build failure after upgrading Poky to 2.5 from
2.2 on qtwayland
Yocto recipe from meta-qt5.

The error looks like :

| Running configuration tests...
| Checking for Wayland client library... yes
| Checking for Wayland cursor library... yes
| Checking for wayland-scanner... yes
| Checking for Wayland EGL library... yes
| Checking for wayland-server... yes
| Done running configuration tests.

I've checked that only pre-condition "features.egl" is failing.
I've my own custom recipe which is providing virtual/egl and is set as
PREFERRED_PROVIDER also.
What is the missing dependency here when virtual/egl is provided?
What exactly is features.egl looking for? ( virtual/egl provides egl.pc )
I've not changed anything in meta-qt5 layer. And the version is 5.9.2
QT5. However, is fails with 5.12 also.


Warm Regards,
