CMP0109

Added in version 3.19.

find_program() requires permission to execute but not to read.

In CMake 3.18 and below, the find_program() command on UNIX would find files that are readable without requiring execute permission, and would not find files that are executable without read permission. In CMake 3.19 and above, find_program now prefers to require execute permission but not read permission. This policy provides compatibility with projects that have not been updated to expect the new behavior.

The OLD behavior for this policy is for find_program to require read permission but not execute permission. The NEW behavior for this policy is for find_program to require execute permission but not read permission.

This policy was introduced in CMake version 3.19. It may be set by cmake_policy() or cmake_minimum_required(). If it is not set, CMake warns, and uses OLD behavior.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
