Build Error: Quantity_ColorRGBA.cxx

Hi everyone,

When trying to build OpenCASCADE 7.4.0 using CMake (and VS2019 x64) with just the modules below I encounter a compilation error in the TKernel project.

BUILD_MODULE_FoundationClasses
BUILD_MODULE_ModelingAlgorithms
BUILD_MODULE_ModelingData

The error is '...src\Quantity\Quantity_ColorRGBA.cxx(18,10): fatal error C1083: Cannot open include file: 'Graphic3d_Vec4.hxx': No such file or directory.'

I manged to get around the issue by patching the file. I changed Graphic3d_Vec4 to NCollection_Vec4<float>. I've attached a patch file for reference.

Is there a formal way to submit pull requests?

Regards,
