C++17 adds the std::byte.
However, there are name collisions between std::byte and the preprocessor
definition of byte defined in rpcndr.h which is included in the windows header.
Currently there is no good fix for this. The best option is to disable
std::byte.

std::unary_function was deprecated in C++11 and removed in C++17.
Apply a patch to vista to remove it and remove it from ITABase code.

Here, a simple removal is enough since the added functionality of
std::unary_function was never used.

The ITAProfiler was moved to the IHTAUtilityLibs.

This was done to bring develop to the state of master, after the multiple reverting.

This reverts commit 2289247b.

The reverted commit was a wrongly reverted merge.
This was probably caused by an old local version.
With this revert, the master branch should be again at the state of v2021.a.

Pulling changes from develop into features/delaunay_triangulation

If the CPM package names are too long, depending on the path to the
base folder, MSBuild throws the error MSB4023.
Meaning, the path is too long.
This reduces the risk of this happening.

Delay the inclusion of the helper function to after the patch is applied.
Otherwise in the initial CMake run, the unpatched version will be used.
This in turn may lead to issues.

When the source files get added in the same CMakeLists.txt where the
target gets defined, the path to the source files is relative
(If not explicitly done in the CMakeLists.txt).
This patch fixes this issue, as these relative paths are already what is
needed for the folders.

This reverts commit 73f2ccf4
