This reverts commit f88b89e3.

Because this package already defines CMAKE_CXX_STANDARD to 11.

Changes in v1.2.1:
- fix backup files inside notebook folder
- fix an issue with the friction cone display
- add quadcopter actuation model

to fix tests in 16.04

Changes in v3.3.2:
- fix packaging

PAL distributions are vanilla Ubuntu, with a few custom packages in /opt/pal.
The OS_VERSION is set to the Ubuntu version suffixed with .PAL.

Adapt the few locations where a test on OS_VERSION == 16.04 or 18.04 is made,
to include 16.04% or 18.04% and match the .PAL suffix.

affected packages:
- py-hpp-baxter

Changes since v1.1.0:
- templatized all the classes and structures with the scalar (for codegen and autodiff).
- fixed a bug in the formulation for the quadrupedal problem (state bounds).
- reduced the compilation time in Python bindings (re-structured the code).
- fixed error in the expected improvement computation for terminal action in SolverFDDP.
- added unittest code for cost classes (included cost factory).
- reorganized the various factories used for c++ unittesting.
- developed the pinocchio model factory for c++ unittesting.
- added unittest code for contact classes (included the contact factory).
- described cost items through shared_ptr.
- described contact items through shared_ptr.
- described impulse items through shared_ptr.
- fixed Gauss-Newton approach for cost num-diff.
- added contact num-diff class.
- used virtual keyword in declaration of derived functions.
- added the unittest code for free forward dynamics action model.
- added the unittest code for contact forward dynamics action model.
- included the cost status in cost sum for global memory allocation.
- included the contact status in cost sum for global memory allocation.
- included the impulse status in cost sum for global memory allocation.
- removed duplication function for retrieving models and datas in solvers (now we do only through shooting problem interface).
- allowed to write internal data of Numpy-EigenPy objects.
- added a general method for setting and getting cost reference.
- added squashing function abstraction.
- added unittest code for testing cost, contact and impulse status.
- moved to CMake exports

Changes since v0.4.0:
- [CMake] fix pinocchio detection
- [CMake] export CURVES_WITH_PINOCCHIO_SUPPORT

Changes since v3.1.2:
- delete duplicate file
- Add the IRIS quadcopter model
- [CMake] Export
