[CMake] QT4_ADD_RESOURCES fails to find dependencies in resource-files with aliases

[Michael G. Hansen]

Hi,

I am using aliases in my Qt-resource-files like this:
<file alias="somefile.ext">filename/on/disk.ext</file>

This prevents QT4_ADD_RESOURCES from finding the dependency on
"filename/on/disk.ext" because the regular expression used for this does
not expect the alias-parameter. I tried to create a new regular
expression which works with the alias-parameter:

FindQt4.cmake from CMake 2.4-patch 5, line 783:
STRING(REGEX MATCHALL "<file( alias=\"[^\"]*\")?>[^<]*" _RC_FILES
"${_RC_FILE_CONTENTS}")

and line 786:
STRING(REGEX REPLACE "^<file( alias=\"[^\"]*\")?>" "" _RC_FILE
"${_RC_FILE}")

I am not that experienced with regular expressions, so maybe somebody
could check them first (they do work for my test-cases, though).

Greetings,
Mike
