Make it possible to call project() in the root CMakeLists.txt (#242)
* Make it possible to call project() in the root CMakeLists.txt
This deprecates the use of setup_project() in favor of:
```
set(PROJECT_NAME "MyProject")
set(PROJECT_DESCRIPTION "...")
set(PROJECT_URL "...")
include(cmake/base.cmake)
project(${PROJECT_NAME} CXX)
```
which is going to be CMake friendly from 3.15 onwards
To do so, including cmake/base.cmake will have the following effect:
- setup a script to call after project() is called
- compute PROJECT_VERSION and restore its value after project() is
called (we cannot use the VERSION argument of project() because we
compute incompatible version numbers)
- setup a hook to call setup_project_finalize() and optionally
setup_project_package_finalize()
* [base] Add a link to minimal example if variables are not defined- Loading branch information
