Public bug reported:

Hg revision 0c73d8794377 does not compile on windows.

First: There appear several linker errors in the tools by the use of the not standard conform __progname variable:
error LNK2019: unresolved external symbol __progname referenced in function panoBasenameOfExecutable	pano13.lib(sys_ansi.obj)

Second: CMake does call ctag-exuberant without to check for existence.
Wrap it around a find_program

FIND_PROGRAM(_ctags ctags-exuberant)
IF(NOT ${_ctags} MATCHES "-NOTFOUND")
    ADD_CUSTOM_COMMAND( OUTPUT ctags POST_BUILD
                        COMMAND ${_ctags} -e *.c *.h tools/*.c
                        WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/
                        COMMENT "Build TAGS file"
                      )
    ADD_CUSTOM_TARGET( TAGS DEPENDS ctags)
ENDIF()
