Bumped Boost to 1.66.0.

This cleans dirty states in submodules which may happen when a
non-existing submodule hash was referenced.

Makes sure to always have the submodule at the desired state.

Conan packages for gcc-6 are build on Ubuntu 17.10. VTK uses getrandom
which is implemented differently depending glibc version, thus the VTK
package for GCC 6 is incompatible to Ubuntu 16.04.

6.2 is the minimum tested compiler by our CI (on envinf1).
6.5 is the default gcc 6 in Ubuntu 16.04 when using the ubuntu-toolchain-r/test PPA.

The option was forgotten.
The WRAPPER command must not be enclosed in double ticks in Tests.cmake.

... such that one can copy and paste the vtkdiff commandline to the
terminal and immediately run it

These jobs running on envinf1 currently fail.

This fixes a CMake error where ${CMAKE_ARGS} was empty.

Stores user-given CMake variables from the recent CMake run into cmake-args file. Install cmake-args file and CMakeCache.txt.

These warnings seems not to appear any longer.

Developer having Conan installed typically also want to use it
for third-party library handling. This avoids strange things
happening when switching Conan to ON from the CMake GUI.

RPath is adapted too.

It is also possible to create CMake lists by not quoting.

Simplified CompilerSetup.cmake a bit.
