error.hunteraddpackage.after.project

What happens

• CMake fatal error with message:

  [hunter ** FATAL ERROR **] Please set hunter_add_package *after* project command
  

Explanation

• First call to hunter_add_package command will trigger calculation of internal variables like config-id / toolchain-id. This must be done after toolchain is loaded (i.e. after first project command) because variables from toolchain like APPLE or ANDROID can be used in configuration file with hunter_config.

What to do

• In general sequence must looks like this (see also error.huntergate.before.project):

  # Check CMake version before any commands
  cmake_minimum_required(VERSION 3.2)
  
  # Load HunterGate module
  include("cmake/HunterGate.cmake")
  
  # Use HunterGate module before first `project` command
  HunterGate(
      URL ...
      SHA1 ...
  )
  
  # Your project
  project(Foo)
  
  # Use hunter_add_package after project command
  hunter_add_package(Boo)
