When trying to build Qt for Python against 5.13 RC2:
CMake Error at /opt/Qt/QtO/5.13.0/gcc_64/lib/cmake/Qt5UiTools/Qt5UiToolsConfig.cmake:37 (string):
  string sub-command REGEX, mode REPLACE needs at least 6 arguments total to
  command.
Call Stack (most recent call first):
  /opt/Qt/QtO/5.13.0/gcc_64/lib/cmake/Qt5UiTools/Qt5UiToolsConfig.cmake:189 (_qt5_UiTools_process_prl_file)
  CMakeLists.txt:263 (find_package)
error: Error configuring pyside2
Traceback (most recent call last):
  File "setup.py", line 296, in <module>
    setup_runner.run_setup()
  File "pyside-setup513i/build_scripts/setup_runner.py", line 157, in run_setup
offending code
string(REGEX REPLACE "[ \t]+" ";" _standard_libraries ${CMAKE_CXX_STANDARD_LIBRARIES})
Seems to affect only prefix builds.
