[Cmake] Undefined ${CMAKE_COMMAND} in POST_INSTALL_SCRIPT

[Andy Cedilnik]

Hi Anton,

When you run CMake install, the variable that were available during
CMake run are not available. What you really want to do is to configure
postInstall.cmake file:

CONFIGURE_FILE(${CMAKE_CURRENT_SOURCE_DIR}/postInstall.cmake.in
  ${CMAKE_CURRENT_BINARY_DIR}/postInstall.cmake @ONLY)

Then you put postInstall.cmake.in to contain:

FOREACH(file @FILES_TO_INSTALL@)
  MESSAGE(@CMAKE_COMMAND@
        "  " ${file} "  " @CMAKE_INSTALL_PREFIX@)
#  EXEC_PROGRAM(@CMAKE_COMMAND@
#               ARGS copy ${file}
@CMAKE_INSTALL_PREFIX@/share/cisst/doc/doxygen)
ENDFOREACH(file)

or 
MESSAGE("Install doxygen files")
FILE(INSTALL 
  DESTINATION "@CMAKE_INSTALL_PREFIX@/share/cisst/doc/doxygen"
  TYPE FILE
  FILES @FILES_TO_INSTALL@)
