In case you're wondering, apparently this bug has been exposed by the changes in the new CMake version that has hit unstable, so this will possibly affect more packages.Intriguing. Note that gtest is intended as the base layer (gmock is built on top of gtest), so it would be a loss to have libgtest-dev pull in gmock. Hopefully there's an alternative fix.
AFAICT the root cause is that upstream exports both GTest and GMock targets to the same export set (GTestTargets), which causes problems if only one of those is installed.
One alternative solution would be to patch the upstream CMake files
and export GMock independently with their own GMockConfig.cmake and
GMockTargets.cmake. Then, for backwards compatibility, you could
add something like
find_package(GMock QUIET)
if(NOT GMock_FOUND)
message(STATUS "GMock not found, targets will not be imported")
endif()
to the end of GTestConfig.cmake.
Cheers
Timo
