When I'm trying to build itom on openSUSE 42.1 with qt5 installed I get following output:

cmake .. -DBUILD_WITH_PCL=OFF -DBUILD_QTVERSION=Qt5

Code that trying to find Qt5 located in ItomBuildMacros.cmake:163 find_package(Qt5 COMPONENTS Core QUIET)

And it works when trying with small hello world project:

CmakeLists.txt

cmake_minimum_required(VERSION 2.8.8)
project(hello-world)

# Tell CMake to run moc when necessary:
set(CMAKE_AUTOMOC ON)
# As moc files are generated in the binary dir, tell CMake
# to always look for includes there:
set(CMAKE_INCLUDE_CURRENT_DIR ON)

find_package(Qt5 COMPONENTS Core QUIET)
message("Qt5 dir:" ${Qt5_DIR})
find_package(Qt5Core QUIET)
message("Qt5 dir:" ${Qt5_DIR})

add_executable(hello_world main.cpp)

qt5_use_modules(hello_world Core)                          

output:

    Thanks for the issue and your fix. Since it is also possible to build a 32bit version on a 64bit machine, we decided to add the BUILD_TARGET64 option. However it would be possible to set it to true per default, since 64bit machines will be used more often.
