eCAL does not build with C++17

[jo-mue]

Same issue as eclipse-ecal/ecal-core#9

Describe the bug
eCAL does not build with C++17. Issue seems to be thirdparty/simpleini.

Minimal example to reproduce

mkdir _build
cd _build

cmake .. -DCMAKE_CXX_STANDARD=17 -DCMAKE_CXX_STANDARD_REQUIRED=ON -DCMAKE_CXX_EXTENSIONS=ON
cmake --build . --parallel --config Release

Issue seems to be same error message as brofield/simpleini#48

Builds fine using Ubuntu 20.04.
