Description
The qt6_create_translation() command contains the following block of CMake code:
list(FIND _lupdate_options "-extensions" _extensions_index)
if(_extensions_index GREATER -1)
math(EXPR _extensions_index "${_extensions_index} + 1")
list(GET _lupdate_options ${_extensions_index} _extensions_list)
string(REPLACE "," ";" _extensions_list "${_extensions_list}")
list(TRANSFORM _extensions_list STRIP)
list(TRANSFORM _extensions_list REPLACE "^\." "") # <----- BUG!
list(TRANSFORM _extensions_list PREPEND "*.")
else()
set(_extensions_list "*.java;*.jui;*.ui;*.c;*.c++;*.cc;*.cpp;*.cxx;*.ch;*.h;*.h++;*.hh;*.hpp;*.hxx;*.js;*.qs;*.qml;*.qrc")
endif()
The list(TRANSFORM ... REPLACE) line has a malformed regular expression. CMake's string parsing would require the backslash to be escaped in order to preserve it as part of the regular expression (to escape the period character). The behavior of the malformed expression will result in the first character of every extension being dropped, not just a leading period character. Any extension that was specified without a leading period would therefore have been incorrectly handled.
