- Migrates legacy text-based FILES, PACKAGES, and EXTERNLIB configuration files to proper CMake format (.cmake extensions)
- Updates CMakeLists.txt files to use modern CMake practices with explicit configurations and target-specific definitions
- Modifies the qt_macro.cmake to work with the new CMake variable-based file management system
- Replaces all `CMAKE_SOURCE_DIR` references with `OCCT_ROOT_DIR` across CMake files
- Updates build templates to use the new root directory variable
- Modifies environment variable configurations to use the flexible root path
- Addition of vcpkg layout configuration with CMake file placement in share/ directory for vcpkg compliance
- Introduction of OCCT_PROJECT_NAME parameter (defaults to "opencascade") for customizing directory structure in vcpkg layout
- Updated environment scripts and build templates to support vcpkg directory structure while maintaining backward compatibility
- Updates architecture detection conditions to include aarch64 and arm64 as 64-bit architectures

Introduces a new "tcltk" feature in vcpkg.json with relevant dependencies.
Updates tcl portfiles and patches to incorporate Tk building, installation, and cleanup.
Modifies CMake and batch environment templates to align with the new TclTk support.
Reorganized resources to keep source part in src and real-time scripts in resource folder.
For the installation result no changes, still installed to src for windows.
New repository for Inspector: https://github.com/Open-Cascade-SAS/Inspector
Documentation and all build process are fully migrated.
"tools" folder keep to share information for some time.
Keep building inspector as before to keep control of API changes via GitHub actions.
Add GitHub Action to build CSharp sample on Windows
Add MFC and Qt sample build actions
Improve CASROOT assignment logic in env.build.sh and env.install.sh for better compatibility with binary directories
OpenGl_FrameBuffer::Init() now creates MSAA render buffer in case if MSAA textures are unsupported.
In this case OpenGl_View::prepareFrameBuffers() creates MSAA render buffer for main content
and non-MSAA FBO for immediate content as blitting of MSAA render buffers into MSAA targets is unsupported by OpenGL ES 3.0.
env.bat.in has been corrected to include path to custom ANGLE (GLES2_DIR)
in front of Qt which might include its own older ANGLE build.
Added new optional dependency - Draco library.
RWGltf_GltfJsonParser now detects KHR_draco_mesh_compression extension,
marks accessor being compressed and redirects to compressed buffer view.
RWGltf_TriangulationReader now handles decoding of buffer view compressed using Draco.
env.bat template for genproj has been modified to allow specifying dedicated folders
with debug versions of libraries (CSF_OPT_LIB64D / CSF_OPT_BIN64D) within custom.bat.
Removed unused CSF_FREETYPE from TKOpenGl.
MACOSX_USE_GLX has been renamed to HAVE_XLIB and now configurable on Linux target.
Xw_Window.hxx now export class on non-Linux platforms.
OpenGl_Window now creates an off-screen EGL surface also in case of
window-less desktop setup (e.g. with disabled Xlib on Linux).
Draw_Window - code has been cleaned up.
Class definition has been unified across platforms when possible.
Unusued constructors have been removed.
Internal header files (MainWindow.h, init.h, etc.) have been renamed to .pxx
to avoid their unexpected distribution in "inc".
Added option USE_FREETYPE to CMake configuration, enabled by default.
Added handling of HAVE_FREETYPE macros.
genproj now overrides env.bat/env.sh on template change.
Added Qt sample OCCTOverview providing examples of use of OCCT API with relevant code and demonstration of results in the viewer.
Off-topic: some unused images are removed from dox/introduction/images/
Added script adm/scripts/android_build.bat and template android_custom.bat.template
intended for automating building routines targeting Android platform.
OpenCASCADEConfig.cmake has been extended to detect "$INSTALL_DIR/libs/$CMAKE_ANDROID_ARCH_ABI/cmake/opencascade" location.
The scripts cmake_gen.bat and cmake_gen.sh have been added to facilitate batch building of OCCT correspondingly on Windows and Linux platforms.
The files build.bat and install.bat are copied to the build directory by cmake configure procedure to enable batch building and installation on Windows platform.
V3d_View::AutoZFit() is now called only before redraw
within methods V3d_View::Redraw() and V3d_View::Update().
Graphic3d_CView now holds Aspect_ExtendedRealitySession object.
Aspect_OpenVRSession implements new interface via optional OpenVR library.
Graphic3d_CView::ProcessInput() - added new interface method
which should be called for processing positional input (head tracking).
Graphic3d_Camera now allows setting custom stereoscopic Projection matrices.
OpenGl_Context::Camera() - context now holds Camera object
in addition to active camera matrices.
genproj.tcl has been extended to handle optional CSF_OpenVR dependency.
- 'Search Qt4' is renamed into 'Search Qt'. Configuration uses Qt5 from now. For Qt4 use CMake configuration.
- 'Build Inspector' check box is added. It causes 'tools' toolkits compilation. Activates automatically 'Search Qt' control.
- Many Tcl procedures are extended with additional parameter to giving a directory of processed toolkits. The default directory is 'src', inspector directory is 'tools'. This way is similar Inspector compilation implemented in Cmake build procedure.
- Dependency libraries in DEBUG are stored in __TKDEP_DEBUG__. Qt requires it as names of debug and release libraries are different.
Build tools are updated to support building with Visual Studion 2019 toolset ClangCL (LLVM clang-cl):
- In CMake builds, use of unsupported option "-std=c++0x" is avoided
- Tool genconf recognizes availability of ClangCL toolset and proposes it in the list
- Tool genproj recognizes new compiler specification VCVER=vclang and generates VS 2019 projects for it
Note that vclang configuration puts binaries to folder "vc14" as it is compatible with vc14 CRT.
Code is updated to build with Clang for Windows without errors and warnings:
- In BVH classes, pure virtual destructors are replaced by empty ones, to avoid bogus compiler warning
- In .lex files, pragmas are added to disable warnings in parser code
- In OSD, signature of function _osd_wnt_set_error() is corrected to avoid warning on incorrect use of va_args (undefined behavior)
- In OSD_Host, OSD_Parallel_TBB, warnings on usage of deprecated function are disabled
- In Quantity_ColorRGBA and ViewerTest_CmdParser, incorrect use of predefined macro __FUNCTION__ assuming it was a string literal is avoided
- In Standard_Macro.hxx, code is reordered to handle Clang for Windows appropriately
- In AdvApp2Var_SysBase.hxx, inclusion of obsolete (MSVC-specific) header file is replaced by Standard_TypeDef.hxx
- In Standard_ErrorHandler.hxx, empty statements added to avoid warning on unused class fields
- In IVtkDraw and ViewerTest, interface is corrected to use actual type avoiding unnecessary type casts
Off-topic: corrections of some errors (uninitialized class fields) reported by VS Code Analysis in TKernel
Added missing HAVE_RAPIDJSON to env.sh.
genconf.tcl has been extended with new option HAVE_E57
which enables looking for E57 and xerces libraries.
Added new libraries CSF_E57 and CSF_xerces to genproj.tcl.
genproj procedure has been extended with new parameters -solution, set to OCCT by default.
Added missing HAVE_RAPIDJSON to env.sh.
Added implicit file path normalization for PRODUCTS_PATH variable,
to avoid genconf.tcl script malfunction on backslashed.
Added adm/qmake/Occt.pro for building OCCT using Qt Creator.
genproj/genconf scripts have been extended with an option defining project format.
Draw_Appli now tries resolving CASROOT/DRAWDEFAULT/CSF_OCCTResourcePath/CSF_OCCTSamplesPath
locations within usual OCCT development/installation environment.
Added missing TKShHealing dependency to TKDraw/DRAWEXE (inherited from TKMesh).
OSD_Process::ExecutableFolder() - added method returning executable folder.
Correct launching custom.sh in env.sh.in.
Correct definition of FFMPEG_DIR in custom.build.bat/sh.in and generation of custom_*.sh (variables CSF_OCCTBinPath and CSF_OCCTLibPath are not empty on the first run)
- samples/tools/TStandalone is removed, to build Inspector out of OCCT, CMake should use tools/CMakeLists.txt fileName
- samples/tools/TInspectorEXE is moved to tools/TInspectorEXE
- TInspectorAPI_Version.hxx provides compilation inspector with earlier version of OCCT.
