Build on macos 10.15.2 (platform SDK has been changed from version 10.14 to version 10.15)

[pryg-skok]

The steps completed successfully:

cmake ../ (from project dir)
make -j4 (with warnings, but for now lets skip them)
qmake hevc_es_browser_gui.pro (from ../utils/hevc_es_browser_gui/)

And then here is an error:

$ make gitinfo
make: *** No rule to make target `hevcesbrowser'.  Stop.
/usr/local/Cellar/qt/5.14.0/mkspecs/features/mac/sdk.mk:22: *** ^.  Stop.
The platform SDK has been changed from version 10.14 to version 10.15.
This requires a fresh build. Please wipe the build directory completely,
including any .qmake.stash and .qmake.cache files generated by qmake.

What can I do here?

Also here are warnings while make:

$ make -j4

The purpose of $ make gitinfo command is to create version_info.h file. During this step the utils/hevc_es_browser_gui/verinfo/verinfo.sh script is used.
As option you can extract version_info.h file from archive(version_info.zip) in attachments and put it into utils/hevc_es_browser_gui/ directory.
After it you can skip the $ make gitinfo step and go to $ make step in utils/hevc_es_browser_gui/ directory.
