prebuild.sh failure

[gggh000]

The instruction in README.md (https://github.com/GPUOpen-Tools/DevDriverTools/blob/master/README.md) does not tell how to solve this build error when invoking prebuild.sh, as a result, it fails to build when following instructions through: "To build on Linux (command line)":

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

CMake Error at /git.co/QtCommon/Scaling/CMakeLists.txt:29 (find_package):
By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5", but
CMake did not find one.

Could not find a package configuration file provided by "Qt5" with any of
the following names:

Qt5Config.cmake
qt5-config.cmake

Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
to a directory containing one of the above files. If "Qt5" provides a
separate development package or SDK, be sure it has been installed.
