error.detect.hunter.root

What happens

• CMake fatal error with message:

  [hunter ** FATAL ERROR **] Can't detect HUNTER_ROOT
  

Explanation

• Hunter need to have directory where all the packages will be installed. Next locations tried (by priority):

  • CMake variable HUNTER_ROOT (high priority; not recommended, since you need to set it for every build)
  • Environment variable HUNTER_ROOT (recommended, full control over directory location shared between all projects)
  • Environment variable HOME (low priority)
  • Environment variable SYSTEMDRIVE (Windows only)
  • Environment variable USERPROFILE (Windows only)

What to do

• Fix your environment. HOME usually defined on Unix-like platforms and SYSTEMDRIVE / USERPROFILE on Windows
• Set HUNTER_ROOT environment variable (restart all CMake GUI’s or terminals to apply changes)
