[CMake] custom_install-target with DESTDIR

[Timenkov Yuri]

Actually, make install calls cmake in command mode to process
cmake_install.cmake file in binary dir. You can move your doxy into separate
component, and call cmake to process installation of particular component.
Something like:

 INSTALL(DIRECTORY html/
   DESTINATION /share/doc/${PROJECT_NAME}
   COMPONENT=doxy)

 ADD_CUSTOM_TARGET(installdoxy
   COMMAND ${CMAKE_COMMAND} -P ${CMAKE_BINARY_DIR}/cmake_install.cmake
-DCMAKE_INSTALL_COMPONENT="doxy" VERBATIM )

Or you can:
1) escape dollar sign to prevent macro expansion at cmake time (but this is
unportable)
2) wrap this call to cmake in separate cmake script (use execute_process
instead), and call it with cmake -P command. This way, environment expansion
will be done during sub-script processing time, that is when you make your
target.
