The absolute paths of certain static dependencies can have spaces in
them. The _qt5_$${CMAKE_MODULE_NAME}_process_prl_file fails to handle
this, and simply replaces all spaces with semicolons, which obviously
breaks the list of dependencies, and a consuming application fails to
link with a message like:
LINK : fatal error LNK1181: cannot open input file 'C:\Program.obj'
This change partially restores the functionality that was added in
102e1822ff specifically the part
that changes qmake to export an additional variable
QMAKE_PRL_LIBS_FOR_CMAKE. This variable has the same content as
QMAKE_PRL_LIBS except it uses a semicolon as a separator, so that
CMake can correctly parse the separate lib entries.
This is much cleaner than trying to parse the original QMAKE_PRL_LIBS
variable with a complicated regular expression.
