Fix for building with GCC and CLang
CMake variable descriptions updated
"Building with CMake" article updated
BuildToolkit.cmake cleaned up and renamed
"TestCases" project and all relating variables removed; custom script added for building environment
DrawAppliInit is copied from occt root to CMake binary dir if the file exists
rebuild platform dependent code by cmake cleaned up
Flex & Bison compiler flags added
RelWithDebInfo OCCT libraries are moved to libi folder; the binary is moved to bini one
CMAKE_BUILD_TYPE is set as Release by-default for a single-configuration generator
env.bat in installation folder has default value of CASDEB that equals to the build type of the last installed OCCT libraries
"building with CMake" article updated
Restore XCode generator.
Add missing dependencies to EXTERNLIB.
genproj.tcl - remove OS:mkdir() - duplicate of wokUtils:FILES:mkdir().
genproj.tcl - use osutils:usedOsLibs() for Code::Blocks.
src/OS - remove unused :LinksoWith() and :CompileWith().
adm/CMPLRS - remove unused CSF_ entities.
Remove config.h related code.
Add executable flag to codeblocks.sh and draw.sh scripts.
Setup ARCH variable using $tcl_platform(pointerSize).
wokdep:SearchLib() - use $tcl_platform(os) instead of $tcl_platform(platform)
for checking Linux-specific library paths.
wokdep:SearchFreeType() - fix misprint in ft2build.h header file name.
wokdep:SaveCustom() - export SHORTCUT_HEADERS to "custom.sh" as well, not only to "custom.bat".
WOK scripts used in generation of MSVC projects are put to adm/genproj.tcl
Batch script genproj.bat added, replacing 'wgenproj' command of WOK.
WOK tool for configuring custom.bat is also copied; it is called by genproj if custom.bat does not exist
Environment variable SHORTCUT_HEADERS can be defined in custom.bat to have headers put in inc just shortcuts to actual headers, instead of copies.
Corresponding option "copy OCCT short-cut headers instead of original one to inc folder" is added to genconf dialog
