Removed cotire PCH
Integrated native PCH by CMake with the same BUILD_USE_PCH flag
Added new option to avoid extra files in 'build/include' folder and replace it by symlink
Symlink creates link to the origin file, it has some benefits from debug and build side.
The CMake parameter for symlink is 'BUILD_INCLUDE_SYMLINK'
MSVC 2022/c++20.
After employed c++20 language standard errors of compilation in intel oneTBB occurred.
To get rid of compilation errors proposed moving on actual (2021.5.0) intel oneTBB occ products and occt.
After migration errors of compilation of TKernel and TMath have been occurred...
...Error occurred if using c++20 standard with new oneTBB 2021.5.0.
The error was:
Error C2672 'tbb::v1::parallel_for_each': no matching overloaded function found TKernel
could be 'void tbb::detail::d2::parallel_for_each(Iterator,Iterator,const Body &)' TKernel
'tbb::detail::d2::parallel_for_each': the associated constraints are not satisfied TKernel
Note, that if we use c++14 or c++17, all ok, error does not occures.
To solve the problem, i have to modify `UniversalIterator` class:
`value_type` instead `UniversalIterator` converted to `IteratorInterface*`
`pointer` = `reference` = `value_type`
Method `DownCast` moved into `FunctorInterface` abstract class.
argument `UniversalIterator& item` of the unary fuctions converted to `IteratorInterface*`.
The proposed solution removes compilation error.
Affected projects: TKernel, TMath
Affected sources: src/OSD/OSD_Parallel.hxx, src/OSD/OSD_Parallel_Threads.cxx
Affected classes: class OSD_Parallel, OSD_Parallel::UniversalIterator, OSD_Parallel::FunctorInterface, OSD_Parallel::FunctorWrapperIter, OSD_Parallel:;FunctorWrapperInt.
Make C++ standard to be enable from cmake settings:
User will be able choosing C++ language standard by selecting cmake variable BUILD_CPP_STANDARD.
For correct working, CMAKE_CXX_STANDARD cmake built-in variable should be available.
To enable CMAKE_CXX_STANDARD, minimum CMAKE version has been updated to 3.1.
Available next standard items:
C++11
C++14
C++17
C++20
C++23
This issue consists from several steps to achive main goal:
1) Configuratiuon, CMake - allow selecting C++ standard.
2) Require minimum CMAKE version 3.1 (for enabling CMAKE_CXX_STANDARD).
3) More flexible CMAKE_CXX_COMPILER_ID identification (fixups previous commit!)
4) Add description of new CMAKE variable `BUILD_CPP_STANDARD` into documentation.
5) Update CMAKE requirements in documentation.
6) Set C++11 standard for several projects.
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.
Added {.cpp} highlighting markers to the C++ code blocks in documentation;
Excessive tildes "~~~~~~~" in code block borders are reduced to required minimum of "~~~~" (4);
Removed obsolete space bars after code block borders;
TCL code blocks are now highlighted with {.php} markers;
Removed excessive {.cpp} highlighting markers appended to non-code blocks such as lists, reports and file content or structure examples;
Minor fixes for tests.md and draw_test_harness.md (whitespace removal and structural fix for "Where:" in code examples);
Minimum HDD space for OCCT updated in introduction.md.
OpenGl_Context now activates Ray-Tracing and arbTboRGB32 for GLES 3.2.
Removed initialization of some uniforms from GLSL code.
Fixed implicit casts within Ray-Tracing shaders.
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/
References to Flex and Bison added
