Summary0014904: Gettext module does not allow installing .po files with the same name from different directories
DescriptionI have the following directory hierarchy:


I would like to have all code handling the translation files in the top-level CMakeLists.txt file so that new translations can be added inside the "po" directory without adding any CMake code.

app/CMakeLists.txt looks like this:

    find_package(Gettext REQUIRED)

    foreach(lang fr es)
        gettext_process_po_files(${lang} ALL
            INSTALL_DESTINATION share/locale
            PO_FILES po/${lang}/test.po)

But this does not work. Running CMake outputs the following error:

CMake Error: Attempt to add a custom rule to output "(...)/app/build/" which already has a custom rule.
Steps To Reproduce- Unpack attached test-case
- Run cmake
Additional InformationI worked around that bug by copying the code from gettext_process_po_files() in my project and adjusting it like this:

diff --git a/Modules/FindGettext.cmake b/Modules/FindGettext.cmake
index 6a1e36e..4b3ada7 100644

Not sure if this is the best fix, though.
