[Geary] Intltool does not accept two --xxx-yyy type option

[Akira Nakagawa <matyapiro31 gmail com>]

In cmake/FindIntltool.cmake
For example
add_cusom_target(geary.xml ALL
    ${INTLTOOL_MERGE_EXECUTABLE}  --xml-style --no-translations 
${CMAKE_SOURCE_DIR}/${po_dir}
                ${CMAKE_CURRENT_SOURCE_DIR}/${xml_id}.xml.in ${xml_id}.xml
)

Console output:Cannot open /tmp/geary/manifest/geary.xml.in: Permission 
denied
This is because of I made geary.application.in read-only.
It shows that cmake recognize the file as outputfile ,not filename.
