Using CMake's fixup_bundle for bundling linux-only application - cmake

Question

We developing some CV application, based of OpenCV, Boost, LibVLC and Caffe. Some of our customers want to deploy it on outdated(or unpopular) Linux distributions, so we must bundle all it's dependencies(and some vlc plugins), most of them can be found in any actual distro, but we have custom build of libcaffe vendored in our repo. So, now i solve it with this bash script:
#!/bin/bash
set -uex
export LD_LIBRARY_PATH=./contrib/caffe.arch32/lib/
function copy_deps {
libs=$(LD_TRACE_LOADED_OBJECTS=1 /lib/ld-linux.so.2 "$1" | cut -d" " -f 3 | sort |uniq | grep -v '^$')
for lib in $libs
do
cp -un "$lib" ./bundle
done
}
mkdir -p bundle
mkdir -p ./bundle/vlc/plugins
cp -r /usr/lib/vlc/plugins ./bundle/vlc
rm -rf ./bundle/vlc/plugins/lua
rm -rf ./bundle/vlc/plugins/gui
rm -rf ./bundle/vlc/plugins/visualization
for plugin in $(find ./bundle/vlc/plugins -name "*.so")
do
copy_deps "$plugin"
done
copy_deps ./detector
cp /lib/ld-linux.so.2 ./bundle
cp ./detector ./bundle
cp ./config.ini ./bundle
mkdir -p ./bundle/config
cp -r ./config/nn ./bundle/config
cp -r ./config/neuron ./bundle/config
echo "LD_LIBRARY_PATH=./ ./ld-linux.so.2 ./detector 2> /dev/null" > ./bundle/run.sh
chmod +x ./bundle/run.sh
zip -q -r bundle.zip bundle
It works fine, but only for executable build(we need shared lib too), only for x86_32 distros. We build our project with cmake, so after reading it's docs i noticed, that fixup_bundle is cmake-way for bundling. All examples and blogs about fixup_bundle is very simple, or related with OSX or Windows. So, i append my CMakeLists.txt
set(CMAKE_INSTALL_PREFIX ${CMAKE_BINARY_DIR})
set(BUNDLE_NAME ${PROJECT_NAME})
set(BUNDLE_PATH "${CMAKE_INSTALL_PREFIX}/${BUNDLE_NAME}")
set(APPS ${BUNDLE_PATH})
list(APPEND DIRS ${CMAKE_INSTALL_PREFIX}/${LIBDIR} ${CAFFE_LINK_PATH} /lib/ /usr/lib)
list(APPEND LIBS)
INSTALL(CODE "
include(BundleUtilities)
fixup_bundle(\"${APPS}\" \"${LIBS}\" \"${DIRS}\")
" COMPONENT Runtime)
And then try to run make install, I noticed that only our custom libcaffe is bundled, no boost, no opencv, no VLC. Why? How to bundle all dependencies?
