Before my fix, the CMakeLists.txt could be sum-up that way:
```cmake
find_package(CGAL REQUIRED)
find_package(Boost QUIET)
if(NOT Boost_FOUND)
message(
STATUS "This project requires the Boost library, and will not be compiled.")
create_single_source_cgal_program( "Point_WKT.cpp" )
# [...]
else ()
message(STATUS "This project requires the CGAL library, and will not be compiled.")
return()
endif()
```
So, on *all platform*, as Boost is mandatory and always found, the
behavior was to display "This project requires the CGAL library, and
will not be compiled." and return, without configuring any target.
I have simplified the `CMakeLists.txt` to the simplest:
```cmake
cmake_minimum_required(VERSION 3.1...3.20)
project(Stream_support_Examples)
find_package(CGAL REQUIRED)
create_single_source_cgal_program( "Point_WKT.cpp" )
```
- `cmake_minimum_required` is mandatory and must be the first line,
- `project` is mandatory,
- `find_package(CGAL REQUIRED)`: no need to test `CGAL_FOUND`, because
CGAL is required anyway. No need to search for Boost, because that is
an implementation detail of CGAL, and the CMake file
`CGALConfig.cmake` deals with that dependency
- and then the declaration of the targets.
