[CMake] FindBoost: FIND_PACKAGE ( Boost COMPONENTS filesystem )

[Mathieu Malaterre]

Hi Philip,

  That's where I stop understanding. I cannot state this:

FIND_PACKAGE ( Boost COMPONENTS filesystem REQUIRED) # ideal

  If I follow your suggestion I need to express an internal
dependencie at user level:

FIND_PACKAGE ( Boost COMPONENTS filesystem system REQUIRED)

  which fails for Boost 1.34 with:

...
CMake Error at Cmake/FindBoost.cmake:894 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.34.1

  Boost include path: /usr/include

  The following Boost libraries could not be found:

          boost_system

  Some (but not all) of the required Boost libraries were found.  You may
  need to install these additional Boost libraries.  Alternatively, set
  Boost_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
  to the location of Boost.
Call Stack (most recent call first):
  CMakeLists.txt:33 (FIND_PACKAGE)
...

Thanks
