Missing files in repo to compile

[chfauck]

I tried to compile linuxdeploy using ci/build.sh, ci/build-in-docker.sh and
manually within my own build directory (mkdir build; cd build; cmake ../" getting the following cmake error
curing configuration:

...:/home/Tools/linuxdeploy/linuxdeploy/build$ cmake ../

After commenting out the BUILD_TESTING lines and add_subdirectory(linuxdeploy-desktopfile EXCLUDE_FROM_ALL) in the CMakeLists.txt files, I get the following:

It seems, that not all required files are committed into the repo. The corresponding folders are empty.
