Description

In Coin, when testing submodules, the stacktraces from gdb or ASAN do not contain source code lines. I filed COIN-1087 for this, see the stacktrace from testing qtvirtualkeyboard on that ticket.

It turns out this is because the libraries are stripped when installed, see for example this snippet from a qtbase build:

agent:2023/09/29 09:22:50 build.go:875: Executing instruction 55 of 86 - ExecuteCommand
agent:2023/09/29 09:22:50 build.go:428: [cmake -DQT_BUILD_DIR=/home/qt/work/qt/qtbase_build -P /home/qt/work/qt/qtbase_build/libexec/qt-cmake-private-install.cmake] 1h40m0s 20m0s false false

agent:2023/09/29 09:22:50 build.go:405: -- Installing: /home/qt/work/install/lib/cmake/Qt6BuildInternals/Qt6BuildInternalsConfig.cmake
[...]

This behaviour was introduced 3 years ago in https://codereview.qt-project.org/c/qt/qtbase/+/315625

CMake: Strip binaries and libraries upon installation

To avoid big artifact sizes, strip the binaries and libraries upon
installation. This achieves stripping similar to ~~QTBUG-69767~~ and
~~QTBUG-81301~~ but arguably in a cleaner CMake way.
