Bug#1123535: `libocct-draw-dev` has implicit dependencies

[andrej730 at icloud.com]

Package: libocct-draw-dev
Version: 7.6.3+dfsg1-7
Severity: normal

Hi! Stumbled upon `libocct-draw-dev` having implicit dependencies.
Consider cmake file below:

```cmake
cmake_minimum_required(VERSION 3.21)
project(test-cmake)

find_package(OpenCASCADE CONFIG REQUIRED)
# main.cpp is not important - just some hello world.
add_executable(main main.cpp)
target_link_libraries(main PRIVATE TKDraw)
```

And the following chain of commands. There are two issues:
- when linking just `TKDraw` target, it also has a bunch of dependencies on other OCCT packages
- after all OCCT packages dependencies are installed, there are also other dependencies like `libtk.so`, `libtbb.so`, etc.

```sh
sudo apt-get install -y libocct-foundation-dev libocct-draw-dev
cmake ..
# Error below logged below
sudo apt-get install -y libocct-modeling-data-dev libocct-modeling-algorithms-dev libocct-visualization-dev libocct-data-exchange-dev
# Error is resolved
cmake ..

# No rule to make target '/usr/lib/x86_64-linux-gnu/libtcl.so', needed by 'main'.  Stop.
make
sudo apt-get install -y tcl-dev

# make[2]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/libtk.so', needed by 'main'.  Stop.
make
sudo apt-get install -y tk-dev

# make[2]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/libtbb.so', needed by 'main'.  Stop.
make
# Build succeds.
sudo apt-get install -y libtbb-dev
```

cmake error for missing OCCT packages:
```
CMake Error at CMakeLists.txt:4 (find_package):
  Found package configuration file:

    /usr/lib/x86_64-linux-gnu/cmake/opencascade/OpenCASCADEConfig.cmake

  but it set OpenCASCADE_FOUND to FALSE so package "OpenCASCADE" is
  considered to be NOT FOUND.  Reason given by package:

  The following imported targets are referenced, but are missing: TKG2d
  TKGeomBase TKG3d TKBRep TKGeomAlgo TKTopAlgo TKShHealing TKMesh TKService
  TKHLR TKBO TKV3d TKFillet TKPrim TKBool TKOffset TKFeat TKOpenGl TKXSBase
  TKMeshVS TKSTEPBase TKSTEP TKIGES TKSTL TKVRML TKLCAF TKXCAF TKRWMesh TKCDF
  TKCAF TKVCAF TKStd TKStdL TKBin TKBinL TKXml TKXmlL TKXDEIGES TKXDESTEP
  TKBinXCAF TKXmlXCAF TKTObj TKBinTObj TKXmlTObj
