# /EHsc : enable C++ exceptions (otherwise exceptions do not work)

# /Zc:__cplusplus : makes sure `__cplusplus` is set to the current C++ version language. Otherwise it is always set to an incorrect wrong value.

# /MP : enable multi-process build with MSBuild (it should be on by default but CMake generates the project files without the right params).

# /W4 : warnings level 4 (default in visual studio projects and recommended minimum level).

# /external:I $ENV{CONDA_PREFIX}: consider the conda env prefix libraries headers as "external" to this project.

# /external:W0 : set the warning level to 1 for external libraries headers (severe warnings, default when unspecified) to only see important warnings coming from dependencies headers.
