Creating installer using cpack and windeployqt - qt

Question

When I execute my CMakelists.txt the target executable is not packaged with neither the autogenerated .zip or the installer, it is located in the root of the build directory. All that is included within the .zip and the installer is the appropriate .dlls, etc. Can someone explain what I'm doing wrong?

The windeployqt copies only the executable's dependencies, so you need to add the executable's installation. Note that if you use DESTINATION . for the destination folder of the binary, this can cause problems when porting the project to other platforms. In such cases it is better to use TYPE BIN instead of DESTINATION .
if(QT_VERSION_MAJOR EQUAL 5)
qt_finalize_executable(translationVerification)
endif()
install(PROGRAMS
$<TARGET_FILE:translationVerification>
DESTINATION .)
##CPack
You can also add include(GNUInstallDirs) before the first install() for portability purposes.
if(QT_VERSION_MAJOR EQUAL 5)
qt_finalize_executable(translationVerification)
endif()
include(GNUInstallDirs)
install(PROGRAMS
$<TARGET_FILE:translationVerification>
TYPE BIN)
##CPack
.
.
.
install(
DIRECTORY "${CMAKE_BINARY_DIR}/qtDeploy/"
TYPE BIN
)
set(CPACK_GENERATOR "ZIP;NSIS")
endif()
