not possible to build nativelly with mingw

[AndreyMlashkin]

To reproduce the problem call: cmake -S . -B ./build/MinGW -D CMAKE_BUILD_TYPE=Release -G "MinGW Makefiles" cmake --build .\build\MinGW\ -j6

Error: internal error in mingw32_gt_pch_use_address, at config/i386/host-mingw32.c:192: MapViewOfFileEx: Attempt to access invalid address.

It can be fixed the same way as it is fixed here: https://github.com/conan-io/conan-center-index/pull/10163

[AndreyMlashkin]

Please, also check compiled libraries names for MinGW. I've got libGraphicsEngineOpenGL_64r.dll.a and libGraphicsEngineVk_64r.dll.a

Diligent provides extensive means for custom build configuration. To enable RTTI, custom_configure_build function should work: it is called after Diligent finishes configuring each target, and RTTI can be enabled if necessary. The function can be defined in the same CMake file before including the Diligent source dir.

Try to update to the latest. Should build in https://github.com/DiligentGraphics/DiligentEngine/commit/432850d5897e65bd6ad4b8ec39716abc973205aa

[TheMostDiligent]

libGraphicsEngineOpenGL_64r.dll.a and libGraphicsEngineVk_64r.dll.a

These are likely export libraries. The dll's should be in the bin folder.

[AndreyMlashkin]

Thank you for a prompt answer and a very quick fix! It works for me

MinGW configuration has been added to CI.
