Summary	0013910: Ninja generator initialization fails if /usr/bin/ninja is not world-readable
Description	CMake tests availability or Ninja by access(, R_OK). This does not make any sense - it's not going to read /usr/bin/ninja, it's going to execute it! "--x" ninja binary results in a cryptic failure message, as shown below.
Steps To Reproduce	$ ls -la /usr/bin/ninja -rwxr-x--x 1 root root 2746829 Feb 13 16:36 /usr/bin/ninja $ cmake -GNinja .. CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. strace shows: access("ninja", R_OK) = -1 ENOENT (No such file or directory) access("/usr/local/bin/ninja", R_OK) = -1 ENOENT (No such file or directory) access("/usr/sbin/ninja", R_OK) = -1 ENOENT (No such file or directory) access("/usr/bin/ninja", R_OK) = -1 EACCES (Permission denied) access("/sbin/ninja", R_OK) = -1 ENOENT (No such file or directory) access("/bin/ninja", R_OK) = -1 ENOENT (No such file or directory)
