* [vcpkg_find_acquire_program] add version check for ninja * Change VERSION to NINJA_VERSION * Missed VERSION change * some more corrections * add missing PACKAGES parameter * add osx hash Co-authored-by: Wolfgang Stöggl <c72578@yahoo.de> * Remove apt/brew package names Co-authored-by: ras0219 <533828+ras0219@users.noreply.github.com> * move supported around and disable it for freebsd * fix small command hickup which does not matter for ninja Co-authored-by: Wolfgang Stöggl <c72578@yahoo.de> Co-authored-by: ras0219 <533828+ras0219@users.noreply.github.com>

## Checks if a Fortran compiler can be found.
