Public bug reported:

libpano 2.9.22 FTBFS against cmake 14.


CMake Error at CMakeLists.txt:32 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

Easily fixed by 
-# require at least cmake 3.0
-cmake_minimum_required(VERSION 3.0)
+# require at least cmake 3.50
+cmake_minimum_required(VERSION 3.5)


BTW: please note that this part

# create TAGS file
ADD_CUSTOM_COMMAND( OUTPUT ctags POST_BUILD
                   COMMAND ctags-exuberant -e *.c *.h tools/*.c
                   WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/
                   COMMENT "Build TAGS file"
is broken and triggers
CMake Warning (dev) at CMakeLists.txt:386 (ADD_CUSTOM_COMMAND):
  The following keywords are not supported when using
  add_custom_command(OUTPUT): POST_BUILD.

  Policy CMP0175 is not set: add_custom_command() rejects invalid arguments.
  Run "cmake --help-policy CMP0175" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.

Afaiui POST_BUILD is only valid for the "add a custom command to a
target" variant of add_custom_command().
