ibs 9f33b387e2 0024888: Refactoring of OCCT CMake meta-project
user sees just dirs of libs, shared libs and headers of 3rdparty products
documentation updated

3rdparty search priority was fixed: 1. user paths; 2. system paths
3rdparty debug usage fixed
vtk search introduced
occt information, generated by wok, was divided onto two files: occt_toolkits.cmake and occt_inc_toolkits.cmake
additional behavior of cmake search for freetype 2.5.1 and above

CMake (version < 3.0) don't know about new place of config/ftheader.h in freetype 2.5.1. There are cases when cmake seeks config/ftheader.h in defined place (3RDPARTY_FREETYPE_DIR variable), doesn't find it and start new search in system places. If system has own freetype header- cmake will find it and 3RDPARTY_FREETYPE* variables will point to different places. This situation is avoided

tcl, freetype, vtk are checked before usage of it (CSF variables usage)
tbb search mechanism was refactored
freetype search is processed by default cmake mechanism
tcl search is processed by default cmake mechanism

3rdparty macro seeks debug libraries (and release if debug ones aren't found); 3rdparty dll is sought in win case only

ADD_SUBDIRECTORY preferred to SUBDIRS

gendoc.bat search for tclsh.exe in user's system

0025141: CMake / MinGW: link recipe fails due to long command

0025146: Porting to Android

OCCT documentation updated. "Building with CMake and ADT for Android" article added

[CMAKE] custom.sh.in uses library variables instead unused dll ones.

-DDEBUG remove from CMAKE_CXX_FLAGS_DEBUG and CMAKE_C_FLAGS_DEBUG

hide unused 3rdparty in android case

also messages of freetype search mechanism slightly updated

Open CASCADE Technology
=======================

This directory contains sources of Open CASCADE Technology (OCCT), a software
development platform providing services for 3D surface and solid modeling, CAD 
data exchange, and visualization. Most of OCCT functionality is available in 
the form of C++ libraries. OCCT can be best applied in development of software 
dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical 
simulation (CAE).

modify it under the terms of the GNU Lesser General Public version 2.1 as 
published by the Free Software Foundation, with special exception defined in 
the file OCCT_LGPL_EXCEPTION.txt. Consult the file LICENSE_LGPL_21.txt included
in OCCT distribution for complete text of the license.

Packaging
---------

You can receive certified version of OCCT code in different packages.

- Snapshot of Git repository: contains only bare sources of OCCT; many C++ 
  files, HTML documentation, and project files / makefiles for building OCCT
  need to be generated.

- Complete source archive: contains all sources of OCCT, including C++ files
  generated by WOK, HTML and PDF documentation, and projects / makefiles for 
  building on all officially supported platforms.

- Binary package (platform-specific): in addition to complete source archive, 
  it includes binaries of OCCT and third-party libraries built on one platform. 
  This package allows using OCCT immediately after installation.

Certified versions of OCCT can be downloaded from http://www.opencascade.org

You can also find OCCT pre-installed on your system, or install it from 
packages provided by a third party. Note that packaging and functionality
of such versions can be different from certified releases. Please consult 
documentation accompanyog your version for details.

Documentation
-------------

Open file doc/html/index.html to browse HTML documentation.

If HTML documentation is not available in your package, you can:

- Generate it from sources. 

  You need to have Tcl and Doxygen 1.8.4 (or above) installed on your system.
  and accessible in your environment (check environment variable PATH).
  Run batch file *gendoc.bat* on Windows or Bash scriot *gendoc.sh* on Linux
  or Mac OS X to (re)generate documentation.

- Read documentation in source plain text (MarkDown) format found in 
  subfolder *dox*

See *dox/dev_guides/documentation/documentation.md* for details.

Building
--------

In most cases you need to rebuild OCCT on your platform (OS, compiler) before
using it in your project, to ensure binary compatibility.

Consult the file *dox/dev_guides/building/building.md* for instructions on
building OCCT from sources on supported platforms.

Version
-------

The current version of OCCT can be consulted in the file
*src/Standard/Standard_Version.hxx*

-----------
