> -- Checking for module 'snappy' > -- Package 'snappy' not found > -- Found Snappy: /usr/lib64/libsnappy.so Seems that pkgconfig checks snappy, I have nothing like that here.
I too get: -- Checking for module 'snappy' -- Package 'snappy' not found -- Found Snappy: /usr/lib64/libsnappy.so -- Found ZLIB: /usr/lib64/libz.so (found suitable version "1.3.1", minimum required is "1.2.6") This appears to come from the root CMakeLists.txt:526, all is well here (I was perhaps jumping the gun in my opening comment as to what was going on) CMake Error at lib/trace/CMakeLists.txt:30 (target_link_libraries): Target "common" links to: Snappy::snappy but the target was not found. Possible reasons include: * There is a typo in the target name. * A find_package call is missing for an IMPORTED target. * An ALIAS target is missing. The later error actually comes from lib/trace/CMakeLists.txt:30. Whether or not that is related to the above package 'snappy' is beyond my cmake knowledge.
Changing line 34 from Snappy::snappy to just snappy makes it "work for me", but that's me stabbing in the dark and hitting lucky.
*** Bug 951994 has been marked as a duplicate of this bug. ***
Thanks, because I still can't reproduce this error but remove "Snappy::" works here too. And it links against (call -lsnappy instead of /usr/lib64/libsnappy.so.1.2.1) I hope to find out what's going on before proposing a patch.
This only happens with USE=gui. Because then /usr/lib64/cmake/Qt6 is in CMAKE_MODULE_PATH and /usr/lib64/cmake/Qt6/FindSnappy.cmake is us. That defines Snappy::Snappy instead of Snappy::snappy. This can be mitigated by passing -DCMAKE_FIND_PACKAGE_PREFER_CONFIG=yes via MYCMAKEARGS or by patching lib/trace/CMakeLists.txt and lib/trace/CMakeLists.txt to use Snappy::Snappy.
I have no issue with gui.
What package provides /usr/lib64/cmake/Qt6/FindSnappy.cmake ?
Thanks Paul Zander, that's qtwebengine. Dan Goodliffe, could you confirm that you have qtwebengine installed and that -DCMAKE_FIND_PACKAGE_PREFER_CONFIG=yes does the job ?

Thanks both, it breaks gtest detection now but it's a detail.
