New 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.
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. CMake version 3.19.0-rc3 warns when the policy is not set and uses
OLD behavior. Use the
cmake_policy() command to set it to
OLD behavior of a policy is
deprecated by definition and may be removed in a future version of CMake.
