Using #define CSG_OCC results in build errors on Windows in release configuration

[Valzul]

Here is my compilation context :

• MSVC 2019 - Release x64
• Windows SDK 10.0.26100.0
• Language Standard ISO C++ 17

When uncommenting #define CSG_OCC in CSG_Adapter.cpp (ln 26), I got multiple errors that seems all related to namespaces :

'csg': is not a member of 'carve'
'CSG': is not a member of 'carve'
'csg': the symbol to the left of a '::' must be a type
'CSG': the symbol to the left of a '::' must be a type
'OP': is not a member of 'carve'

Steps to reproduce :

• Download the current source code
• Open the solution IfcPlusPlus.sln with Visual Studio 2019
• Check "Release" build
• Add the include path to OpenCascade library
• Uncomment #define CSG_OCC in CSG_Adapter.cpp (ln 26)
• Hit compile

However this work for the Debug configuration, yet I can't seem to detect what configuration of the project causes this behaviour, can someone point me to what may be wrong ?
