[CMake] Empty CPack variables

[Pau Garcia i Quiles]

Hello,

I am using CMake 2.8.11.2 on Windows to build and package some software. If
I do this, it works fine:

   set(CPACK_PACKAGE_DESCRIPTION_SUMMARY "Wt binary build")
   set(CPACK_PACKAGE_VENDOR "emweb bvba")
   set(CPACK_PACKAGE_DESCRIPTION_FILE
"${CMAKE_CURRENT_SOURCE_DIR}/ReadMe.txt")
   set(CPACK_RESOURCE_FILE_LICENSE
"${CMAKE_CURRENT_SOURCE_DIR}/Copyright.txt")
   set(CPACK_PACKAGE_VERSION_MAJOR "3")
   set(CPACK_PACKAGE_VERSION_MINOR "3")
   set(CPACK_PACKAGE_VERSION_PATCH "1")
   set(CPACK_PACKAGE_INSTALL_DIRECTORY "Wt
${CPACK_PACKAGE_VERSION_MAJOR}.${CPACK_PACKAGE_VERSION_MINOR}.${CPACK_PACKAGE_VERSION_PATCH}")
   set(CPACK_GENERATOR "ZIP;NSIS")
   include(CPack)

But if I add this line before include(CPack):

  set(CPACK_PACKAGE_FILE_NAME
"${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}")

then CPACK_PACKAGE_NAME, CPACK_PACKAGE_VERSION and CPACK_SYSTEM_NAME are
empty and the file is generated as "---.zip" / "---.exe". Am I doing
something wrong? (I want to add a couple more variables in the
CPACK_PACKAGE_FILE_NAME variable to specify compiler and compiler version,
that's why I'm composing CPACK_PACKAGE_FILE_NAME)

Thank you
