Use of Cotire tool is introduced for acceleration of CMake builds, by usage of precompiled headers. CMake option BUILD_USE_PCH is added to enable / disable use of precompiled headers When precompiled headers are used, additional compiler macros are defined globally in the build system to avoid problems due to different order of included files: - NOMINMAX is defined on Windows to prevent defining "min" and "max" as macros by windows.h - STRSAFE_NO_DEPRECATE and _SCL_SECURE_NO_WARNINGS are defined on Windows to prevent declaring functions of standard C library as deprecated by #pragma, and other warnings in system headers - GL_GLEXT_LEGACY and GLX_GLEXT_LEGACY are defined to ensure that only OCCT's own glext.h is used - __STDC_FORMAT_MACROS is defined to have standard C print format macros always defined Code is corrected to avoid conflicts with system headers and in case of compiling together as unity builds (partially): - Some locally defined variables in TKV3d, TKHLR are renamed to be unique - Duplicated definitions of macros and global functions are eliminated in TKSTEP - Useless header WNT_UInt.hxx is removed - Usage of local variables conflicting with X11 macro is avoided in Draw_Viewer.cxx - Local variables in AIS_ConcentricRelation.cxx are renamed to avoid conflict with macros defined in windows.h - HXX files containing code are renamed to PXX or merged with corresponding CXX files. IVtkTools classes are corrected to avoid compiler warnings disabled in non-PCH builds by inclusion of VTK headers. Useless pragmas disabling warnings on MSVC are removed
