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
