[CMake] Problem with cpack in latest cmake v3.3.1 and ninja

[Gonzalo]

I upgraded my cmake just recently and I am using the Ninja generator.
The compilation and linking seems to work fine.
However, when I run make package, I get the following:

[2/2] Run CPack packaging tool...

CPack Error: Problem compressing the directory

If I try running one of the md5sum lines manually, I get:

  cmake -E md5sum "/usr/bin/cmake" -E md5sum 
"/media/Linux/code/applications/mrViewer/BUILD/Linux-3.16.0-45-generic-64/Release/tmp/_CPack_Packages/Linux/DEB/mrViewer-v2.9.0-Linux-64/usr/local/mrViewer-v2.9.0-Linux-64/bin/docs"

No such file or directory

It seems the latest cmake is not accepting multiple -E commands.  Or the 
ninja generator is creating an incorrect run line.
